Populate DetailsView From GridView Select DataKeyNames

Here i'm explaining how to Populate DetailsView From GridView In Asp.Net based on selection of a record in GridView using Multiple DataKeyNames

Populate multiple detailsview from gridview select
In this example GridView is populated from a table called Website using SqlDataSource.

I have defined multiple(3) comma separated DataKeyNames Property in GridView source.

These DataKeyNames properties will be used to fetch the record related to respective DataKey from 3 tables to populate 3 DetailsViews.

Write below mentioned code in SelectedIndexChanged Event of Gridveiw.

C# CODE
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        string App_id = GridView1.DataKeys[GridView1.SelectedIndex]["ResponseID"].ToString();
        SqlDataSource3.SelectParameters.Clear();
        SqlDataSource3.SelectParameters.Add("ResponseID", App_id);
        DetailsView2.DataBind();

        string Source_id = GridView1.DataKeys[GridView1.SelectedIndex]["Source_id"].ToString();
        SqlDataSource4.SelectParameters.Clear();
        SqlDataSource4.SelectParameters.Add("Source_id", Source_id);
        DetailsView3.DataBind();
    }


VB.NET CODE
Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs)
 Dim App_id As String = GridView1.DataKeys(GridView1.SelectedIndex)("ResponseID").ToString()
 SqlDataSource3.SelectParameters.Clear()
 SqlDataSource3.SelectParameters.Add("ResponseID", App_id)
 DetailsView2.DataBind()

 Dim Source_id As String = GridView1.DataKeys(GridView1.SelectedIndex)("Source_id").ToString()
 SqlDataSource4.SelectParameters.Clear()
 SqlDataSource4.SelectParameters.Add("Source_id", Source_id)
 DetailsView3.DataBind()
