Writing data to template columns (ddl and txt box)

[Michael]

Having a heck of a time setting one template field based on the choice in another:

See attached image:

When I select a "Worker", it that worker is bBrown I want to set the "On TimeCard" to "Yes" for any other user set it to "No"

Seems simple enough.

Template field for dropdown looks like this:

<telerik:GridTemplateColumn FilterControlAltText="Filter TemplWorker column"
HeaderText="Worker" UniqueName="TemplWorker">
<EditItemTemplate>
<telerik:RadDropDownList ID="RadDropDownList5" runat="server"
DataSourceID="sqlWorkers" DataTextField="EmployeeNumber"
DataValueField="EmployeeID" DropDownHeight="300px"
DropDownWidth="150px" ExpandDirection="Up" Width="110px"
SelectedText='<%# Bind("LaborPerformedBy") %>' CausesValidation="False"
OnSelectedIndexChanged ="RadDropDownList5_SelectedIndexChanged"
AutoPostback="False"
>

</telerik:RadDropDownList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator6" runat="server"
ControlToValidate="RadDropDownList5" ErrorMessage="Worker is required."
Font-Size="XX-Small" ForeColor="Red" SetFocusOnError="True">*</asp:RequiredFieldValidator>
</EditItemTemplate>

<ItemTemplate>
<asp:Label ID="Label4" runat="server"
Text='<%# Eval("LaborPerformedBy") %>' Width="75px"></asp:Label>
</ItemTemplate>
<HeaderStyle Width="145px" />
</telerik:GridTemplateColumn>

I have tried so many different things not even sure what is what anymore or which event to hook   :-)


I was able to get the value of the dropdown in itemdatabound but I still cannot set the "On Timecard" field.

Any direction is appreciated.

Hi Michael,

Please try the following code snippet to set a column text based on dropdownlist select:

ASPX:

<telerik:GridTemplateColumn HeaderText="Worker" UniqueName="TemplWorker">
    <EditItemTemplate>
      <telerik:RadDropDownList ID="RadDropDownList1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RadDropDownList1_SelectedIndexChanged". . .>
      </telerik:RadDropDownList>
    </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="On Timecard">
    <EditItemTemplate>
        <asp:Label ID="Label1" runat="server" Text="No"></asp:Label>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadDropDownList1_SelectedIndexChanged(object sender, DropDownListEventArgs e)
{
  RadDropDownList droplist = (RadDropDownList)sender;
  GridEditableItem edit = (GridEditableItem)droplist.NamingContainer;
  Label lbl = (Label)edit.FindControl("Label1");
  if (droplist.SelectedText == "bBrown")
  {
   lbl.Text = "Yes";
  }
  else
  {
   lbl.Text = "No";
  }
}

Thanks,
Princy
