When the button is pressed the following method is called:
protected void Edit_Text(object sender, EventArgs e)
{
Button btn = sender as Button;
if (btn != null)
{
editField = btn.ID.Replace("btn", "");
btn.Visible = false;
//Getting and storing rowindex
TextBox txt = this.FindControl("txt" + editField) as TextBox;
txt.ReadOnly = false;
txt.BackColor = System.Drawing.ColorTranslator.FromHtml("#FFFFB2");
txt.Focus();
comment = txt.Text;
//Further methods unnecessary for this question
}
}
As you can see, the prefix is stripped from the controls and then added in when necessary to find the right control at the point, therefore the string for the FindControl method is correct and should return a a TextBox.
However, by stepping through I can see that it is passing an empty TextBox instance rather than the expected result or a null.
I have already tried the findcontrol function on the table itself, I used 'this' as a second check but both yielded the same results.
I suspect the html table is a problem as in another method I am having issues finding a button manually in the html table:
Button editbtn = tblMain.Rows[GetRowIndex(hdnRowIndex.Value)].Cells[2].Controls[0] as Button;
Which is returning a null despite there always being a cell button in that cell for each row
EDIT - Here is the binding that is performed
private void bindData(DataTable dt)
{
if (dt.Rows.Count > 0)
{
foreach (DataColumn col in dt.Columns)
{
TextBox txt = tblMain.FindControl("txt" + col.ColumnName) as TextBox;
if (txt != null)
{
txt.Text = dt.Rows[0][col].ToString();
}
}
}
}
Your problem is here:
this.FindControl("txt" + editField) as TextBox;
FindControl is not recursive and can only find immediate children of the control it was called on. Here you are calling it of the page instance, so it only seeks through immediate children of the page in the control tree (presumably this is only a form element).
What you need to do is to pick a server-side control right above your textboxes/buttons and run FindControl of it. For instance, let's say it is your table, which is declared as:
<table>
<%--...all the content from the post goes here...--%>
</table>
Make this table server-side:
<table id="TheTable" runat="server">
and then call FindControl on this table:
TextBox txt = TheTable.FindControl("txt" + editField) as TextBox;
You can of course keep the table client-side, and use some control that wraps this table. Just make sure that in between your control and the textbox in question there are no other server-side controls.
<table style="width:100%; margin-left:auto; margin-right:auto;" id="tblTst" runat="server">
<tr>
<td>
<h2>
Vehicle Information
<asp:Label ID="lblTest" Text="THis is a Test" ForeColor="Salmon" runat="server" />
<asp:Button ID="btnTest" CommandArgument="0" OnClick="btnTest_click" runat="server" Text="Test" />
</h2>
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblTst2" Text="This is also a Test" ForeColor="Salmon" runat="server" />
<asp:Button ID="btnTest2" CommandArgument="1" OnClick="btnTest_click" runat="server" Text="Test" />
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblMsg" runat="server" />
</td>
</tr>
</table>
protected void btnTest_click(object sender, EventArgs e)
{
Button btn = sender as Button;
string comment = "";
string editField = "";
if (btn != null)
{
editField = btn.ID.Replace("btn", "");
btn.Visible = false;
//Getting and storing rowindex
foreach(HtmlTableCell cl in tblTst.Rows[Convert.ToInt32(btn.CommandArgument)].Cells)
{
foreach (Control ctrl in cl.Controls)
{
if(ctrl is Label)
{
Label txt = new Label();
txt = ctrl as Label;
txt.BackColor = System.Drawing.ColorTranslator.FromHtml("#FFFFB2");
txt.Focus();
comment = txt.Text;
lblMsg.Text = comment;
return;
}
}
}
//Further methods unnecessary for this question
}
}
}
This is what I came up with, this does work; however it is a fairly dirty way to do this, I'm sure you can clean it up quite a bit. This is only intended as a starting point. The big different is that you need to look in the cell for the control not in the table or page, also the cell is an htmltable cell not just a table cell.

I have a ListView in .NET that is hooked up to various CRUD methods, the select method that accepts a value doesn't seem to be working. The Data Source is supposed to be taking the value from a drop down list control, taking the selected value. when I do the configure data source method in visual studio, I select this method for my select operation:
EntReqList_byID(Int32 programID), returns List<EntranceRequirementInfo>
Then when I define parameters in the next part of the wizard, I pick control as a parameter source, with the control ID set to CertificateList, which shows the programID as the parameter from CertificateList.SelectedValue.
When I run the page, and select an item from the CertificateList, and click "Show Program", all my data is pulled except for that in the list view. My code is as follows:
The top of my page:
Please select the program credential type:
<asp:DropDownList ID="InitialCredential" runat="server" AutoPostBack="True" OnSelectedIndexChanged="InitialCredential_SelectedIndexChanged">
<asp:ListItem>[Select]</asp:ListItem>
<asp:ListItem>Certificate</asp:ListItem>
<asp:ListItem>Diploma</asp:ListItem>
<asp:ListItem>Degree</asp:ListItem>
</asp:DropDownList>
</p>
<p>
Please select a program:
<asp:DropDownList ID="CertificateList" runat="server" DataSourceID="CertificateODS" DataTextField="ProgramName" DataValueField="ProgramID" Visible="false"></asp:DropDownList>
<asp:DropDownList ID="DiplomaList" runat="server" DataSourceID="DiplomaListODS" DataTextField="ProgramName" DataValueField="ProgramID" Visible="false"></asp:DropDownList>
<asp:DropDownList ID="DegreeList" runat="server" DataSourceID="DegreeListODS" DataTextField="DegreeName" DataValueField="DegreeID" Visible="false"></asp:DropDownList>

Is there something I am missing to make it get the programID, and populate the data?
In my website I have a dropdown list with 2 values. I am trying to write this code to hide textbox by onselectIndexChange event without refreshing the page.
for this goal I used Update panel but on dropDownList select there is no change in textboxs visibility.

I have the following databound DataList inside an UpdatePanel which updates whenever a selection is made from a DropDown menu.
However, if nothing is retrieved from the db table, I get a blank section.
What I would like to do is display the same table which is inside the ItemTemplate along with text - i.e. 'Admin Not Found', 'Email Not Found'....etc for the EmptyDataTempate...
I've noticed that the EmptyDataTemplate doesn't exist for a DataList, but I don't want to use a different control.
Is there a way to do this? Sample code appreciated. Thanks!

You can add a simple function that return a msg if the field is null.
You call a function like
<%#GetWithMsg(Container.DataItem, "CompanyEmail", "e-mail n/a")%>
for example
<asp:TextBox Text='<%# GetWithMsg(Container.DataItem, "CompanyEmail", "e-mail n/a") %>' CssClass="input input1" ID="co_email"
Width="150" runat="server" ReadOnly="True" />
and the code behind.
protected string GetWithMsg(object oItem, string cField, string TheMsg)
{
var TheData = DataBinder.Eval(oItem, cField);
if(TheData == null)
return TheMsg;
else
return TheData.ToString();
}
not tested but mybe you can try
'<%# !string.IsNullOrEmpty(Eval("CompanyEmail").ToString()) ? Eval("CompanyEmail") : "Email Not Found" %>'
explicit casting might be better in terms of performance than eval though
e.g.
'<%# !string.IsNullOrEmpty(((System.Data.DataRowView)Container.DataItem)["CompanyEmail"].ToString()) ? ((System.Data.DataRowView)Container.DataItem)["CompanyEmail"].ToString() : "Email Not Found" %>'
hope itll help
Sample Edit:
protected void BindData()
{
DataTable dt = DAL.GetData(...
if(dt.Rows.Count == 0)
{
dt.Rows.Add(dt.NewRow());
}
DataList.DataSource = dt;
DataList.DataBind();
}
I got a table with 2 nested tables inside that display my two repeaters. My repeaters display Home and office addresses respectively. The problem is that whenever I add a new record in one repeater, the other repeater table's display gets messed up. Like if I add a record in rpt1 , then table for rpt1 moves up and table for rpt2 goes down..ie the headers do not display in one single line . They move up and down when records are added or deleted. WHat I want is these headers to be fixed so if I add new records or delete records, the headings of both repeaters display on the same line...How do I fix this ? Hope its not confusing.

Use css attribute valign and set its value to top like this <td width="50%" valign="top">.
<table width="100%" cellpadding="0" cellspacing="0">

For headers look to use the <th> element, this will keep them at the top of the table.
Put the <table> tags you do have outside your repeater controls, make sure the repeater only renders a single row and the same for the header.
Unless you have good reason consider just wrapping the two tables in <div> tags as nested tables really don't work ideally for layout.
