So I believe if you change your code to explicitly call DataBind() after setting DataSourceID, things will work fine. Example:

this.grdEnglishCurrencies.DataSourceID = "ObjectDataSource1";
this.grdEnglishCurrencies.DataBind();

Still i m getting same error. No Effect !!!!!!!!!!

Hello,
I think I know what is going on - you will probably need to explicitly rebind the grid after you set the DataSourceID property. DataSourceID is just a strig property and does not initiate rebinding automatically - binding is delayed up until the OnPrender method.
So I believe if you change your code to explicitly call DataBind() after setting DataSourceID, things will work fine. Example:
this.grdEnglishCurrencies.DataSourceID = "ObjectDataSource1";
this.grdEnglishCurrencies.DataBind();

Thanx Rumen Stankov

Still i m not able to solve my problem. I have used object Data source now. But still same problem. Here is my new code:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{

//this.BindGridData();
this.grdEnglishCurrencies.DataSourceID = "ObjectDataSource1";//if i remove it from here even then i get same error
}

}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
//this.BindGridData
this.grdEnglishCurrencies.DataSourceID = "ObjectDataSource1";//if i remove it from here even then i get same error
}

protected void grdEnglishCurrencies_InitializeDataSource(object sender, UltraGridEventArgs e)

{
this.grdEnglishCurrencies.DataSourceID = "ObjectDataSource1";
}

Hello,
I was able to reproduce the same problem locally. It seems that if you are manually binding the grid (e.g. not using declarative datasources), you need to bind the grid very early in the page life-cycle in order to avoid the exception you are getting - you need to re-bind the grid in the Page_Init (OnInit event of the Page) event handler. You can also try using the InitializeDataSource event of the grid - it gets automatically called when datasource is needed and my actually be the better solution. Moving my binding code to OnInit solved the problem in my case, hopefully this approach is applicable in your case as well, or you can try InitializeDataSource as well.

You can find a related thread with this and other suggestions that helped here:
http://forums.infragistics.com/forums/p/3026/17064.aspx
I also recommend the following blog post for additional information how databinding in UltraWebGrid works in general:

Please, let me know if this helps.
