Hi.
I use RadGrid with paging. All columns in grid are GridButtonColumn. When I handle ItemCommand event  e.Item.DataItem == null but  e.Item.IsDataBound == true. How can I get my databound object?

Hello Anatoliy,

The safest way to retrieve the data object from the source is by looking directly into the source table or view. Generally, you can convert your e.Item to a GridDataItem and take a unique cell value from it that you can use for querying your database. This way, you can ensure that the retrieved data source item is represented by your GridDataItem.

Hi.
I do this:
protected
void grid_ItemCommand(object source, GridCommandEventArgs e)

{

GridDataItem Item = e.Item as GridDataItem;

foreach (TableCell item in Item.Cells)

{

string str = item.Text;

}

str == " " for all cells

I do this:
protected
void grid_ItemCommand(object source, GridCommandEventArgs e)

{

GridDataItem Item = e.Item as GridDataItem;

string s = Item["ServiceName"].Text;

but s again is " "

maybe it happens because I bind my grid via NeedDataSource event

Hi Anatoliy,

Most probably you have a control in this cell. When a TableCell Controls collection is not empty the cell Text will be empty.

Hi Anatoliy,

Try accessing the text of a GridButtonColumn as shown below.


ASPX:
 <telerik:GridButtonColumn DataTextField="ProductName" ButtonType="linkButton" UniqueName="BtnCol"></telerik:GridButtonColumn> 
                

CS:
 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    { 
        GridDataItem item = (GridDataItem)e.Item; 
        LinkButton lnkbtn = (LinkButton)item["BtnCol"].Controls[0]; 
        string strtxt = lnkbtn.Text; 
    } 
 

Thanks
Shinu.
