PostBack inside of radgrid add record

[Kevin]

I have a requirement to postback inside of the radgrid add new record event, What I have is a service that looks up a name, when the user picks a name I want a bunch of labels to be filled out via a postback.  can this be accomplished inside the add record event.  i also use to edit records as well but this is easy to fill.

This si my searcher that needs to post back and fill in labels on the add new record event of the radgrid.
 <EditFormSettings EditFormType="Template">
                                    <FormTemplate>
                                        <table style="width:80%;background-color:antiquewhite;border:double;margin-left:auto;margin:auto">
                                            <tr>
                                                <td>
                                                   <asp:TextBox ID="txtSearch" runat="server" Width="260px" AutoPostBack="true"></asp:TextBox>
                                                    <asp:AutoCompleteExtender ID="txtSearch_ACE" runat="server" DelimiterCharacters="" Enabled="True" ServicePath="~/iMACService.asmx" ServiceMethod="FindName"
                                                    TargetControlID="txtSearch" UseContextkey="true" MinimumPrefixLength="2" OnClientItemSelected="Selected" EnableCaching="true" CompletionInterval="1" />
                                                    <asp:TextBoxWatermarkExtender ID="txtSearch_WME" runat="server" TargetControlID="txtSearch" WatermarkText="Enter Last Name First Name" WatermarkCssClass="WaterMark" />
                                                </td>
                                            </tr>

{
    TextBox txt = sender as TextBox;
    GridEditFormItem item = txt.NamingContainer as GridEditFormItem;
    // Based on Textbox value get the other information here
    // if your label in FormTemplate then by using below code you can able to fint it

Hi jayesh,

Ok tried this but I get and error on the setting of the text, it says it cannot find the control.  It seems that if I am setting the item as gridEditFormItem to the textbox  it will never get the other labels that I need to fill out.  I tried to use a generix grideditformitem but it does not seem to like this either. 

Object reference not set to an instance of an object.   is the error and it hits on the label line.

Protected Sub txtSearch_TextChanged(sender As Object, e As EventArgs)
       If HFPersId.Value > String.Empty Then
           Dim txt As TextBox = TryCast(sender, TextBox)
           Dim item As GridEditFormItem = TryCast(txt.NamingContainer, GridEditFormItem)

           Dim Fname As Label = TryCast(item.FindControl("txtFname"), Label)

           Fname.Text = "Kevin"
       End If
   End Sub

Hi Kevin,

Make sure that the label you are trying to set is there in the editform. Here is a code I tried which works fine. Can you share the code where you have labels.

ASPX:

<EditFormSettings EditFormType="Template">
    <FormTemplate>
        <asp:Label ID="txtFname" runat="server" Text="Label"></asp:Label>
        <asp:TextBox ID="txtSearch" runat="server" Width="260px" AutoPostBack="true" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
    </FormTemplate>
</EditFormSettings>

VB:

Protected Sub TextBox1_TextChanged(sender As Object, e As EventArgs)
    Dim txt As TextBox = TryCast(sender, TextBox)
    Dim item As GridEditableItem = DirectCast(txt.NamingContainer, GridEditableItem)
    Dim Fname As Label = DirectCast(item.FindControl("txtFname"), Label)
    Fname.Text = "Kevin"
End Sub

Thanks,
Princy
