In Asp.Net we sometimes require to find TextBox, DropDownList or other controls placed inside GridView so that we can get their value and update if needed.In this article i have tried to explain how to  find TextBox, DropDownList or other controls in GridView in asp.net


Suppose you have a GridView grdEmp  and you want to find a control e.g TextBox or DropDownList placed inside the GridView on RowUpdating event then here is the code:

<asp:GridView ID="grdEmp" runat="server" >

</GridView>

C#.Net Code to find TextBox, DropDownList or other controls in Gridview in asp.net

protected void grdEmp_RowUpdating(object sender, GridViewUpdateEventArgs e)

    {

        DropDownList ddlDept = (DropDownList)grdEmp.Rows[e.RowIndex].FindControl("ddlGrdDept");

        TextBox txtcity = (TextBox)grdEmp.Rows[e.RowIndex].FindControl("txtCity");

    }

VB.Net Code to find TextBox, DropDownList or other controls in Gridview in asp.net
