my ASP.NET GridView does not bind correctly

I have an ASP.NET GridView supposed to exec a SQL Query.
The query is never executed so I strongly suspect there is a binding issue somewhere.
Here is the aspx code:
<asp:SqlDataSource ID="i_sdsGv" runat="server" ConnectionString="<%$ ConnectionStrings:XXX %>"
SelectCommand="INCOHERENT QUERY IN ORDER TO TRIGGER AN EXCEPTION"
SelectCommandType="Text"
<SelectParameters>
<asp:QueryStringParameter Name="MyTableId" QueryStringField="MyTableId" />
</SelectParameters>
</asp:SqlDataSource>
...
<asp:GridView ID="i_gv" runat="server" AutoGenerateColumns="False" DataKeyNames="MyTableId"
DataSourceID="i_sdsGv" OnRowDataBound="i_gvOptionChoix_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:TextBox ID="i_tbName" runat="server" Text='<%# Bind("MyTableName") %>' />
</ItemTemplate>
</Columns>
<EmptyDataTemplate>
NO ROWS TO DISPLAY
</EmptyDataTemplate>
</asp:GridView>
I am 100% sure that if the query string is inexact, an exception is triggered.
In my case, no exception is triggered so the query is not executed.
I get the NO ROWS TO DISPLAY text.
The only obvious binding that I can think about is between the DataSource and the GridView. It does look OK to me.
So I would suspect an issue with :
DataKeyNames="MyTableId" ?
My i_gvOptionChoix_RowDataBound method is empty at the moment but I think it does not matter at this time?
What am I missing so the app actually attempts to execute the query?
Thx in advance for your kind assistance

GridView display text rather than foreign key

I have just started to learn how to use the Gridview Control to display SQL data. I have been able to get almost everything to work except for displaying the more user friendly information for one of my data fields that I populate from a lookup table. The entire concept of the page I want to be able to Update, Insert and Delete new records too and for some reason I could not get these options to work when I was using the SqlDataSource so I use LinqDataSource and all is now working (except I haven’t figured out Insert yet…a separate question)
I am also using the controls tabs in Visual Studio to choose and edit the attributes of the controls so kind of using the wizards and not hand coding the example.
What I cannot figure out is how to make my column with employeetypeid that contains the foreign key from the employeetypelookup table to show the employeetype text value for the user so this makes more sense. I found a “Walkthrough: Displaying a Drop-Down List While Editing in the GridView Web Server Control“ and this works perfectly. When I go into edit mode the dropdownlist shows the employeetype text and when I choose a different type, the appropriate employeetype id gets stored in the database.
So how can I modify something (the Datasource???) to display the employeetype text in the DataGrid.
<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="SNRmain.SNRmainDataContext" EntityTypeName="" OrderBy="lastname, preferredfirstname" Select="new (personnelid, lastfirstname)" TableName="masterpersonnellastpreferreds"></asp:LinqDataSource>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="LinqDataSource1" DataTextField="lastfirstname" DataValueField="personnelid">
</asp:DropDownList>
<asp:LinqDataSource ID="LinqDataSource2" runat="server" ContextTypeName="SNRmain.SNRmainDataContext" EnableDelete="True" EnableInsert="True" EnableUpdate="True" EntityTypeName="" TableName="tblappointmentdates" Where="personnelid == #personnelid" OrderBy="startdate desc">
<WhereParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="personnelid" PropertyName="SelectedValue" Type="Int32" />
</WhereParameters>
</asp:LinqDataSource>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="snrappointmentid" DataSourceID="LinqDataSource2">
<Columns>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
<asp:BoundField DataField="startdate" HeaderText="startdate" SortExpression="startdate" />
<asp:BoundField DataField="endingdate" HeaderText="endingdate" SortExpression="endingdate" />
<asp:TemplateField HeaderText="employeetypeid" SortExpression="employeetypeid">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList2" runat="server" DataSourceID="LinqDataSource3" DataTextField="employeetypetext" DataValueField="employeetypeid" SelectedValue='<%# Bind("employeetypeid", "{0}") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("employeetypeid") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="apptcomment" HeaderText="apptcomment" SortExpression="apptcomment" />
<asp:BoundField DataField="dateentered" HeaderText="dateentered" SortExpression="dateentered" />
</Columns>
</asp:GridView>
<asp:LinqDataSource ID="LinqDataSource3" runat="server" ContextTypeName="SNRmain.SNRmainDataContext" EntityTypeName="" OrderBy="employeetypetext" Select="new (employeetypeid, employeetypetext)" TableName="tblemployeetypelookups">
</asp:LinqDataSource>
I have tried to modify the LinqDataSource2 to include a statement like the one below but that does not work and I get an error that does not make sense to me. "System.Web.Query.Dynameic.ParseException: Syntax error.
<asp:LinqDataSource ID="LinqDataSource2" runat="server" ContextTypeName="SNRmain.SNRmainDataContext" EntityTypeName="" Select="snrappointmentid,
personnelid, startdate,
endingdate, employeetypeid,
tblemployeetypelookup.employeetypetext
from tblappointmentdates
join tblemployeetypelookups on tblappointmentdates.employeetypeid = tblemployeetypelookups.employeetypeid" TableName="tblappointmentdates" Where="personnelid == #personnelid">
<WhereParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="personnelid" PropertyName="SelectedValue" Type="Int32" />
</WhereParameters>
</asp:LinqDataSource>
thanks in advance.

Ok if I understood correctly what you should do is to pass the employeetypeid in a function and retrieve the text and bind that to control like this.
from
<asp:Label ID="Label1" runat="server" Text='<%# Bind("employeetypeid") %>'></asp:Label>
to
<asp:Label ID="Label1" runat="server" Text='<% #GetEmployeeName(Eval("employeetypeid"))%>' runat="server" />
so now GetEmployeeName is a server function you would write to fetch name from id.
protected string GetEmployeeName(int employeetypeid)
{
//What ever is the way to query and return from here
}
Also as side note I noticed you do naming like Label1 which is very poor practice.

ASP Dropdown list not changing the value

First off, I'm still getting my web dev legs under me. I've combed through piles of SO posts, blogs, newsgroups and articles and I cannot seem to fix my problem. It's very similar to at least 10 different posts I've looked at.
I have an ASP gridview, which acts as a display and a select column. When you click select it throws the data into a detailsview. I have one field that needs to be a drop down box, but whenever I change the value and click update the value that is sent to the command is the original value.
Page Markup:
<asp:TemplateField HeaderText="Planner Name">
<ItemTemplate>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="cboCurrentPlanner" runat="server" DataSourceID="plannerDataSource"
DataTextField="planner_name" DataValueField="planner_id" SelectedValue='<%# Eval("planner_id") %>' AutoPostBack="true" ></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
</Fields>
<FooterStyle BackColor="#CCCC99" ForeColor="Black" />
<HeaderStyle BackColor="#333333" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="Black" HorizontalAlign="Right" />
</asp:DetailsView>
sqlDataSource:
SelectCommand="SELECT vendor_key, vendor, planner_name, street, city, state_country, planner_id, country FROM V_MAP_MarkerInfo WHERE (vendor_key = #vendor_key)"
UpdateCommand="MAP_usp_webUpdatePlanToVendor"
UpdateCommandType="StoredProcedure" onupdating="mapDetailSource_Updating" >
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="vendor_key"
PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="vendor_key" Type="String" />
<asp:Parameter Name="planner_id" Type="Int32" />
<asp:Parameter Name = "vendor" Type="String" />
</UpdateParameters>
</asp:SqlDataSource>
<asp:SqlDataSource ID="plannerDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:vendor_mapConnectionString %>"
SelectCommand="SELECT [planner_id], [planner_name] FROM [MAP_planners]"
OldValuesParameterFormatString="original_{0}">
</asp:SqlDataSource>
I won't post the stored procedure code, I know that is working. The original value is the only value that makes it to the parameter.
I've tried all sorts of combinations of <%# Bind/Eval() %> postbacks but I can't find the right combination.
When I click select, I want the current planner to be selected in the dropdown list. When I select a new planner and click update I would like the planner to update. I'm not sure why this is so difficult or what I have royally screwed up to make it difficult but I am at my wits end. If at all possible, I would like an explanation of what is going on and not just the magical line of code that makes it work.
Flabbergasted is an understatement.
EDITS: ViewStateEnbabled="true" added to dropdownlist, the selectedIndexChanged event is firing.
EDIT AGAIN: Changed the planner_id to <asp:ControlParameter> added monitors to DetailsView1_OnDataBind and MapDataSource1_updating and the value is all over the place. but I can't see where it's being reset.

Do you have EnableViewState="false" set on the #Control or #Page settings? If viewstate is not enabled the control will always have the default value as the selected value. This can be set at the aspx level or the ascx level.
http://msdn.microsoft.com/en-us/library/ms972976.aspx

So I am a complete idiot, the DetailsView DataKeyNames property was not set correctly. I had accidentally added "planner_id" as a key from the wizard.
The code was fine all along. Thank you to everyone for trying, but I am a lost cause!

bind sqldatasource result to textbox c#

I have a SqlDataSource that returns 1 field (1 row) for an ID. I would like to get that result and display it in a TextBox. I would normally do it using a stored procedure (since the stored procedure is already created), but I was thinking SqlDataSource would be easier. Is there a way to bind that result onto my TextBox?
<asp:SqlDataSource ID="ds1" runat="server"
ConnectionString="<%$ ConnectionStrings:conn1%>"
ProviderName="<%$ Connectionstrings:conn1.ProviderName %>"
SelectCommand="sp_1"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter Name="accountID" Type="Int32" />
<asp:Parameter Name="activitydate" Type="DateTime" Direction="Output" />
</SelectParameters>
</asp:SqlDataSource>

You cannot just bind textbox like that, there is no DataSourceID property on textbox.
My suggestion, you may create a DataList using that DataSource and on ItemTemplate, you can do:
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind ('activitydate') %>'></asp:TextBox>

It looks like you've already configured your sqldatasource to utilize a stored procedure. In order to bind activitydate to a textbox, please consider using:
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind ('activitydate')
%>'></asp:TextBox>
Hope this helps:)

Dropdown list bound to object data source - how to update on a button click

This is probably something really stupidly simple..
I have a drop down list bound to an object data source. I have set AppendDataBoundItems to true so that I can have an initial select.
<asp:DropDownList ID="Accommodations1" runat="server" AutoPostBack="true" DataTextField="AccommodationTypeDescription" DataValueField="Id" OnDataBound="Accommodations1_DataBound" onSelectedIndexChanged="Accommodations1_SelectedIndexChanged" Width="200px" DataSourceID="AccommodationDs" AppendDataBoundItems="true">
<asp:ListItem Text="Select" Value=""></asp:ListItem>
</asp:DropDownList>
<asp:ObjectDataSource ID="AccommodationDs" runat="server" OldValuesParameterFormatString="original_{0}" SelectMethod="ListByPropertyId" TypeName="PropertyAccommodationController">
<SelectParameters>
<asp:Parameter Name="PropertyId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
I have a button which adds an accommodaton - so after that happens I need the dropdown list to update to include the new accommodation. So I've tried calling databind on the dropdownlist, and databind on the datasource - and nothing is making this dropdown list update.
eg. PropertyAccommodations1.DataBind();
Could someone please let me know what I'm doing wrong. Originally I thought it was due to an update panel issue.. but I've removed the update panel and it still doesn't work (and checked the master page doesn't include an update panel).
Thanks!!

You can subrcibe to DDL OnDataBound and add the "Select" item
Accommodations1.Items.Add(new ListItem("Select",""));

In the button click, after you call .DataBind() on the DDL, you can then do
Accommodations1.Items.Add(new ListItem("Select"));

Thanks for the quick responses - have implemented
Accommodations1.Items.Insert(0,new ListItem("Select",""));
as I specifically wanted it at the top :)
I still think it would be neater to have this default item in the source of the page - but that AppendDataItems is tripping me up.
