In my form I have drop down list that displays products
and a textbox that should display the price for the selected product
My question is how can I add datasource into the textbox ?
You can add a Event-Handler to the drop-down list that gets called, when the user selects a different value in the drop-down list.
Then simply change the value of the textbox in the event-handler method.
Hope this helps, please comment if you need more information.
I solved the problem !
I used datalist insted of textbox and I configured its datasource
to retrive the price for any chosen product from the drop down list
<ItemTemplate>
Price:
<asp:Label ID="PriceLabel" runat="server" Text='<%# Eval("Price") %>' />
<br />
<br />
</ItemTemplate>
</asp:DataList>

If u want u change the Drop down list value of second based on first Drop down list selected value.. that should write in selected Index changed event with auto post back = "true"
It should be so freakin' easy, but why is my data not displaying? I even used the AccessDataSource wizard to configure the datasource and I still can't get it to show what is there. Here is my markup:
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="~/App_Data/TravelJoansDB.mdb"
SelectCommand="SELECT ID, Destinations FROM [Destinations]">
</asp:AccessDataSource>
<asp:Label ID="CurrentDestLabel" runat="server" Text="What is currently displayed:" />
<br />
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Destinations") %>'/>
I don't get any errors or anything, just nothing displays for my "Label1". Any thoughts?
I am not quite sure, but I think you try to show a whole List in a single label...
perhaps your command need something like "Select top 1 Destinations FROM [Destinations]"
So you make sure, that you have only one Element selected...
Make sure to include any databound controls in a DetailsView, FormView, Gridview, etc...
I have a listview which is databound by a list of objects.
In the listview, i have a dropdownlist on each item. Which is filled in the .._itemcreated event.
<asp:ListView ID="ListList" runat="server">
<ItemTemplate>
<asp:TextBox ID="ListItem" runat="server" Text='<%# Eval("CompanyName") %>'></asp:TextBox>
<asp:DropDownList ID="ddlAccountManagers" AutoPostBack="True" runat="server" />
<br />
</ItemTemplate>
</asp:ListView>
Depending on which item, i have to set the selectedvalue of the dropdown. But how do I do this?
How do I access the current items values in the itemcreated event?
Since you are able to fill the dropdownlist, I assume you already have access to it.
ddlAccountManagers.Items.FindByText("TextToSelect").Selected = True
or
ddlAccountManagers.Items.FindByValue("ValueToSelect").Selected = True
You could try this one:
ddlAccountManagers.SelectedValue="value you want to be selected"
In the list of objects you have, I suppose that each object will be associated with an AccountManager. An AccoutManager logically would have an id, that will distinguish him/her from the rest of account managers. Then you have to put this value as the selected value.
I am building a website for a class and have come across an error that I can not find the solution to. I have a dropdownlist on the page that displays the cutomer name and sets the selected value to the customer id selected from a sqldatasource (data tables from access database - fig1) (this works fine as I have tested it before I added the second sqldatasource). I add a datalist control to the page and a second sqldatasource for the datalist to bind to. I configured the datasource using the configure data source wizard as shown in fig2. I then use the wizard to test the data returned by the query and see that it works, the wizard shows that the data that I wanted is returned. So I bind the datalist to the data source and now the itemtemplate (in the html source view) contains data bound labels that will show the values:
Products.Name:
<asp:Label ID="Products_NameLabel" runat="server" Text='<%# Eval("Products.Name") %>' />
<br />
Technicians.Name:
<asp:Label ID="Technicians_NameLabel" runat="server" Text='<%# Eval("Technicians.Name") %>' />
<br />
Incidents.DateOpened:
<asp:Label ID="Incidents_DateOpenedLabel" runat="server" Text='<%# Eval("Incidents.DateOpened") %>' />
<br />
Incidents.DateClosed:
<asp:Label ID="Incidents_DateClosedLabel" runat="server" Text='<%# Eval("Incidents.DateClosed") %>' />
<br />
Incidents.Description:
<asp:Label ID="Incidents_DescriptionLabel" runat="server" Text='<%# Eval("Incidents.Description") %>' />
The labels are now bound to the data returned from the second source....or so it would seem. When I run it and select a customer that should return the data that is being selected in the sqldatasource select statement, my program crashes and gives this error:
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Products'.
I do not understand why it is saying that the datarowview does not contain a column with that name when the sqldatasource clearly returns it when I test it in the wizard. Can anyone please help?
P.S. Sorry for the links to imgur...apparently you have to have a higher rep to post pictures
I tried this and the generated HTML was NOT prefixed with the table name like in your code.
I hand-added the table name and reproduced your error.
So, if you have duplicate column names like you do, you need to modify the SQL statement to use an alias:
Products.Name as Products_Name
