2 controls with Autopostbacks

[Pavel Brokhman]

1. We have RadGrid Control.
2. Each row has EditTemplate.
3. There we have TabControl with 2 tabs
4. 1st tab contains TextBox, Label and Button

I am going below to simplify the requirements:
1. When we click on the button we call Popup Window. (ButtonClick with Postback)
2. When we change some value in TextBox, we put for instant Success or Failed messages in Label (TextChanged with Postback).

Here is scenario I am trying to achieve:
1. Change the value in TextBox
2. Click on the button or on second tab
3. Results - some message in Label + (window is Pop-upped or 2nd tab is opened)

What happens is:
We have to click twice on button to get the result.

Is there any other way, except PostBacks to solve it using RadControls?

I removed 90% of the code and left only the part where we are using RadGrid. Look at the one of the TextBoxes and his validator. For instance textbox "itemID". This textbox validated by CustomValidator. If the value is incorrect everything work OK when ItemCommand is not executed. However, when value is OK and IsValid is true, I would like to be able to run ItemCommand when I click on save ("imbUpdate" imageButton).

Hello Pavel,

I went through your code and I observed that you have different ValidationGroup names for the CustomValidator and the Update button. Does it make any difference if you set the controls ValidationGroup property to the same name?
I also used the provided code to prepare a sample project. Could you please check it and let me know if it works as desired or if I missed something from your logic out?

All the best,

Your example works exactly the same as mine with the problem I try to solve.
Here is the scenario to reproduce it:
1. Click on edit button for "101"
2. Change the value to "101f"
3. Click save. Validation works and show the message
4. Change the value back to "101"
5. Click save. Validation works and message removed. However, save didn't happen, although the value is right
6. You have to click save again to make it happen.

Or another scenario:
1. Click on edit button for "101"
2. Change the value to "101f"
3. Click cancel. I don't want any validation messages, just to cancel it.

Hello Pavel,

I followed the listed steps and was able to replicate the behavior. However, the same issue can be replicated if you place the problematic controls outside the grid as well. For instance if the page is as below:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default4.aspx.cs" Inherits="Default4" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:TextBox Enabled="true" ID="itemID" MaxLength="20" runat="server" Width="90px"
        AutoPostBack="true" CausesValidation="true" ValidationGroup="valGrpItemID" />
    <asp:CustomValidator ID="custValItemID" Display="Dynamic" class="txtNormal" runat="server"
            ValidateEmptyText="true" OnServerValidate="custValItemID_ServerValidate" ValidationGroup="valGrpItemID"
            Text="<br/>Invalid Expense Type/Item No." />
    <asp:ImageButton ID="imbUpdate" runat="server" ImageUrl="~/Images/Update.gif" CommandName="Update"
        ToolTip="Accept Changes" ValidationGroup="valGrpItemID" OnClick="imbUpdate_Click" />
    <asp:ImageButton ID="imbCancel" runat="server" ImageUrl="~/Images/Cancel.gif" CommandName="Cancel"
        ToolTip="Cancel Edit" OnClientClick="if(!confirm('Are you sure you want to cancel any changes?')) return false;"
        CausesValidation="false" OnClick="imbCancel_Click" Style="width: 12px" />
    </form>
</body>
</html>

The this behavior is due to the TextBox AutoPostBack property set to true. Because when you change the TextBox text and without going out of the TextBox focus click on either of the buttons, the TextBox TextChanged event is fired instead of the buttons Click event. And because the TextBox causes validation on postback, validation is fired even when you click on the Cancel button.

Therefore I suggest that you turn the AutoPostBack property of the Textbox back to false. You can use additional button to perform the actions of the TextChanged event handler instead.

I hope this helps.

Best wishes,

1. I know where the problem is. Why you think I called the topic this way.
2. I never said that the rpblem is the grid. I just used this forum hoping that there is more elegant solution by using Telerik controls to solve it. Because I know the solution to this problem by using JScript. On Client click of the button I put the ID of the button in hidden field. On the server I just check if there is any ID there and imitate button click on server.
3. It is not the solution to remove Autopostback for us, because as I said before, button click it is the only 1 possobility.
