Do you mean that Datagird retains the Data during post-back which you don't want?

yes frnd
thnx for advance

If the Viewstate is enabled then the DataGrid will persist the Data during postback. if you want to clear the DataGrid then set the Datasource property to Nothing and do a DataBind.
DataGrid.DataSource = Nothing<br />
DataGrid.DataBind()

i wrote this code in form load
DataGrid1.DataSource = Nothing
DataGrid1.DataBind()
but not working.if i refresh the form the old data also added with new data.
plz give some other solution

I guess this is the only way to clear the DataGird. How is it possible to display the Old Data when you set the DataSource property to Nothing?. I guess there is something terribly wrong with your system. How about this alternative...
DataGrid1.Visible = False
If this alternate is also not suitable for you requirement then just put a breakpoint in each event and function in your page and do a step-wise execution and try to trace and fix the problem.

What do you mean by this? There is nothing called old data or new data in DataGrid. Whatever Data that you Bind to the DataGrid will be shown. Did you try to trace the Code?

Are you talking about page caching?

Are you just usng AJAX, or relying on the Microsoft AJAX library ? When does the value disappear ? Odds are high that when you do a postback, the values, which were not in viewstate, will be lost. You should populate the second list based on the selected index of the first list during a postback.

Hi friends
i have one a.aspx and one usercontrol.
I have defined one public property in code behind file in user control.
I have one link button in form and I load dynamically usercontrol in the page on click of this button.
My code is here
PlaceHolder.Contrls.Add(LoadControl("usercontrol.ascx"));
But I want to access property.
How can I do this?
Thanks in advance.
best regard

Iterate over the controls in PlaceHolder, and find the one that is an instance of the user control. If you want to access it right away, do this:
userControl control = LoadControl("usercontrol.ascx");
control.property = value;
PlaceHolder.Controls.Add(control);
This code is obviously not copied from your code, it has a typo, it's best to paste the code so we see exactly what you're running.

i have done it by following code
UserControl uc = ((UserControl)LoadControl("UserControls/ucEditLetter.ascx"));
Type ucType = uc.GetType();
System.Reflection.PropertyInfo ucPropInfo = ucType.GetProperty("LetterID");
ucPropInfo.SetValue(uc, "value", null);
divLoadFCK.Controls.Add(uc);
