Set value of DataRowView

[zach davis]

Hey Everyone,

I have hit a hard spot here.....I have no idea why this isn't working.

Code

DataRowView dataItem = (DataRowView)commandEventArgs.Item.DataItem;
int _value= Convert.ToInt32(dataItem.Row["valueToRetrieve"]);
dataItem.Row[NUMBER] = GetDisplay(value);

NOTE: I have change some variable names for organizational purposes......

I don't know why this isn't working.  It has worked for me in the past.  Am i not calling a method I need to call.  I know the GetDisplay() returns the right value.  However, this isn't being displayed when the screen comes back up. 

Any thoughts....

Thanks,

Hi,

You can access the DataItem property only in ItemDataBound event of grid. I am not sure about in which event you are trying the code.

Have you tried calling Rebind() method of grid after setting the values?

Shinu,

Thanks for response.  I should have specified before -- I am calling this code from with inside the ItemDataBound event.  I suppose I could call RebindGrid().  However, I don't think that would be good from within the itemdatabound event.  Would that create an infinite loop?

Thanks,

Hello Zach,

Indeed, calling the Rebind() method into the RadGrid.ItemDataBound event handler will cause infinite loop.  Also to achieve the desired functionality you could try using the following code snippet:

void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
   if (e.Item is GridDataItem)
   {
       DataRowView dataItem = (DataRowView)e.Item.DataItem;
       int _value = Convert.ToInt32(dataItem.Row["valueToRetrieve"]);
       (e.Item as GridDataItem)["ColumnUniqueName"].Text = GetDisplay(value).ToString();
   }
}

Additionally I am sending you a simple example which demonstrates the desired functionality.

I hope this helps.
