Use SelectRow to convert Grid values to Session Variables

[RickC]

I need to set up a RadGrid to search a large customer database. Once I have found a particular customer I need to select that RadGrid Row and set the different column values of the Row as Session Variables to be available on another page (this is shopping cart application on the Admin part of the site where Admins can add an order for the customer). I've browsed through a bunch of the documentation but haven't been able to figure out how to do this. Any suggestions?

Hi,

You can loop through the items collection in the PreRender event and check for the matching condition e.g. using the DataKeyValue and select the item as shown below:

C#

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem dataItem in RadGrid1.Items)
        {
            if (dataItem.GetDataKeyValue("CustomerID").ToString()=="ALFKI")
            {
              dataItem.Selected=true;
               Session["Value"]= dataItem["CompanyName"].Text;
            }
        }
     }

Hope this helps.

Princy, thanks for the reply. I am not familiar with when the Prerender event occurs in the RadGrid lifecycle but I would assume that it happens before the Grid is rendered so I am not sure how that would allow me to select an existing row from the RadGrad and then access the row values to create Session Variables.

Hello Rick,

To see more information on the sequence of events in the control, you can refer to the following article:

If the PreRender event handler is not a good place for you, you can move the logic to another event
