How to retrieve the selected row column value in RadGrid?

[Ana]

Hi,

I have nested RadGrid and I want to get the value of a particular column from the selected row of matertableview( in other words clicking on the expand/collapse). Because, I need to use that for the child items query.

Below is my code-snippet:

​protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
            // code???
                    string customerid= dataItem.GetDataKeyValue("CustomerId");
 }

Thanks a million.

Hi Ana,

Please try the below C# code snippet to access the DataKeyValue of expanded row.

C#:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == "ExpandCollapse")
    {
        GridDataItem dataItem = e.Item as GridDataItem;
        string customerid = dataItem.GetDataKeyValue("CustomerID").ToString();
    }
}

Thanks,
Shinu.

Hi Shinu,

I couldn't get the value of string customerid.  It is still showing up as null.

Hi Ana,

I guess you have a hierarchy grid, please make sure you have set the DataKeyNames property in the aspx for the tables and try accessing them with the table name as shown below:

ASPX:

<MasterTableView DataKeyNames="CustomerID"  Name="Customers">

C#:

if (e.CommandName == "ExpandCollapse" && e.Item.OwnerTableView.Name == "Customers")
{
  GridDataItem dataItem = e.Item as GridDataItem;
  string customerid = dataItem.GetDataKeyValue("CustomerID").ToString();
}

Thanks,
