Update fields in insert form template based on the selected index of a radcombobox!

[Panayiotis Pelekanos]

Hi there,

How can i update fields in my grid when in insert template form mode?
I have a radcombobox bound to a datasource that displays cost types eg: M,M1,M2.....
When the user selects lets say M1 then i want some textboxes of the form eg employee portion,company portion  to updated using calculated data that i will include in my code.
 
I ques my calculations will be placed at :

Protected Sub costtyperad_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

    End Sub

but how do i access and set values in the other textboxes that are bind in my datasource?

Thanxs in advance
Panos

Hello Panos,

You can try out the following code to access a TextBox in the FormTemplate on SelectedIndexChanged event of the combobox:
aspx:

 <EditFormSettings EditFormType="Template" >
            <FormTemplate>
                <telerik:RadComboBox ID="RadComboBox2" AutoPostBack="true" DataSourceID="SqlDataSource2" DataTextField="ProductName"  runat="server" OnSelectedIndexChanged="RadComboBox2_SelectedIndexChanged">
                 </telerik:RadComboBox>

                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            </FormTemplate>
 </EditFormSettings>

cs:

protected void RadComboBox2_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

RadComboBox comboBox = (RadComboBox)o;

GridEditableItem dataItem = (GridEditableItem)comboBox.NamingContainer;// To access the InsertFormItem

TextBox txtBox = (TextBox)dataItem.FindControl("TextBox1");

txtBox.Text = "CustomText";

}

Thanks
Princy.

Hi Princy,
I have allready done that

<telerik:RadComboBox ID="costtyperad" Runat="server" DataSourceID="COSTTYPE"
                                                                 DataTextField="CostType" DataValueField="CostType"
                                                                 AppendDataBoundItems="True" AutoPostBack="True"
                                                          onselectedindexchanged="costtyperad_SelectedIndexChanged"
                                                          SelectedValue='<%# Bind("CostType") %>'>
                                                                 <Items>
                                                          <telerik:RadComboBoxItem runat="server" Text="-Please Select Cost Type-"
                                                                  Value="-Please Select Cost Type-" />
                                                                  </Items>
                                                                 <CollapseAnimation Duration="200" Type="OutQuint" />
                                                             </telerik:RadComboBox>

My question is on what to include in the subroutine:

Protected Sub costtyperad_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

end sub

The values returned from the combobox are : M,M1,M2,M3 etc
If the user selects M1 then 3 textboxes must filled with some variable data based on the selection.
So how can i make a case scenario on the combobox selection in order to update the template form textboxes:

Here is just some pseudocode i have prepared in order to understand better my requirement:

Dim ACmp As String, AEmp As String, A1Emp As String, A2Emp As String
        Dim MCmp As String, M1Cmp As String, M2Cmp As String, MEmp As String, M1Emp As String, M2Emp As String








        MCmp = 21.36
        M1Cmp = 32.04
        M2Cmp = 42.72
        MEmp = 0
        M1Emp = 10.68
        M2Emp = 21.36
        If Left(selection, 1) = "A" Then
            Select Case selection.ToString
                Case "A"
                    EmployeePortion.Value = AEmp
                    CompanyPortion.Value = ACmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
                Case "A1"
                    EmployeePortion.Value = A1Emp
                    CompanyPortion.Value = ACmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
                Case Else
                    EmployeePortion.Value = A2Emp
                    CompanyPortion.Value = ACmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
            End Select
        ElseIf Left(selection, 1) = "M" Then
            Select Case selection.ToString
                Case "M"
                    EmployeePortion.Value = MEmp
                    CompanyPortion.Value = MCmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
                Case "M1"
                    EmployeePortion.Value = M1Emp
                    CompanyPortion.Value = M1Cmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
                Case Else
                    EmployeePortion.Value = M2Emp
                    CompanyPortion.Value = M2Cmp
                    total.Value = EmployeePortion.Value + CompanyPortion.Value
                    YearlyAmount.Value = 12 * total.Value
            End Select
        End If
