Get DataKeys value for multiple DataKeyNames in a GridView


To retrieve the values from a DataKeyNames collection, you can use the following things. You can use the following code to get the DataKeys.

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with “foreach” or for any GridView event like OnRowDataBound.

Here, You can input multiple values for DataKeyNames by separating with comma (’,’). For example, DataKeyNames=”ProductID,ItemID,OrderID”

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

Hope it helps

Good Luck
