Avnish asked on 27 Feb 2015, 09:35 AM

Hello Telerik Team,

Im trying to make an email management using telerik with 3 Tier architecture in asp.Net.

I have created a master page. Then a web page using this master page. I have to show a grid which could display "From", "To", "Message", createdOn etc on the grid. I have attached edit and delete button through item template image button. I am using a panel below the RadGrid so that when i click on edit template button this panel will open. this panel contains label names and their corresponding text boxes.
Now when i click on edit template image button....the values from the corresponding row should be filled in the textboxes of the down panel.
But when i click on the edit template image button, the objects in between and that corresponding textbox 's object too have found (got assigned) the value (as i can check it through break functionality of visual studio) but the value is not displaying on that textbox.

And another problem is that nothing happens when i click on another paging option or pagesize. plz fix it too.

please help me in this way as soon as possible.

Im sending you the code of main.master, NTier.aspx & NTier.aspx.cs

Hello Avnish,

From the provided code I noticed that both a RadAjaxManager and RadAjaxPanel controls are used to ajaxify the page content. Have in mind that this is not recommended and will break the AJAX functionality as explained here. Please remove the RadAjaxManager from the page and test it again.

Additionally have in mind that when advanced data-binding is used(using the NeedDataSource event) there is no need to manually assign a data source to the grid inside the PageIndexChanged and PageSizeChanged event handlers. That said you can remove them and move the BindData logic inside the NeedDataSource handler.

C#:

protected void NTierGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{

RadGrid radNTGrid = (RadGrid)source;

DataTable ds = new DataTable();

ds = objEmailBL.GetEmailData("119");

if (ds != null)

{

radNTGrid.DataSource = ds;

}

If the above does not prove helpful and the issue persists please remove the RadAjaxPanel as well and test whether a server-side exception is thrown.
