How can we find the control in the row grid view command?

There is actually no Row in the GridViewCommandEventArgs, so you will need to get the row from the command source naming container

GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);

      

        
        
        
      

    

then you can use

TextBox myTextBox = row.FindControl("MyTextBoxId") as TextBox;

      

        
        
        
      

    

Hope this helps!

If u want to find the control in the command line Use

controlname controlId=(controlname)e.FindControl("controlId"); 

      

        
        
        
      

    

For example, if u wants to find a lable with Id lbl , then use.

Label lbl = (Label)e.Row.FindControl("lbl");

      

        
        
        
      

    

You can use "CommandArgument" in your control with "CommandName". Here are 2 arguments:

<asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" CommandArgument='<%# Container.DataItemIndex + ";" + Eval("idinterlocuteur") %>'>

      

        
        
        
      

    

Then, in your code behind, you can get the arguments:

string[] arg = e.CommandArgument.ToString().Split(';');
int index = Convert.ToInt16(arg[0]);
string idinterlocuteur = arg[1];

      

        
        
        
      

    

And now you can find your controls:

CheckBox Check1 = GridView1.Rows[index].FindControl("MyCheckboxinrow") as CheckBox;

      

        
        
        
      

    

If you are using usercontrols on your gridview item then ((Control)e.CommandSource).NamingContainer

your gridviewrow may not return.

In this case, I used the following code to get the current line:

var c = ((Control) e.CommandSource).NamingContainer;
while (c.GetType() != typeof(GridViewRow))
{
    c = c.Parent;
}
var currentRow = (GridViewRow) c;

      

        
        
        
      

    

It's not pretty, but it works.

 if (e.CommandName == "UpdateStat")
        {
            HiddenField IDHiddenField=(HiddenField)GridView1.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("IDHiddenField");
            TextBox CurrentStatDesTextBox=(TextBox)GridView1.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("CurrentStatDesTextBox");}

      

        
        
        
      

    

GridViewRow gvr = (GridViewRow) ((Control) e.CommandSource) .NamingContainer; int rowIndex = gvr.RowIndex;

        string Cat_name = (GridView1.Rows[rowIndex].FindControl("TxtName") as TextBox).Text;
