问题:

How can I find the control in the row command of grid view?

回答1:

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

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

then you will be able to use

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

Hope this helps!

回答2:

if your using LinkButton

 LinkButton ctrl = e.CommandSource as LinkButton;
   if (ctrl != null)
    {
        GridViewRow row = ctrl.Parent.NamingContainer as GridViewRow;
        TextBox txtDescription = (TextBox)row.FindControl("txtDescription");
    }

回答3:

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

Label lblProdId = (Label)row.FindControl(“lblproductId”);

回答4:

If u want to find a control in row command Use

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

For example if u want 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 2 arguments :

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

Then in your code behind you can get arguments :

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

And now you arguments to find your controls :

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

If you are using usercontrols in your gridview itemtemplate then ((Control)e.CommandSource).NamingContainer might not return your gridviewrow.

In that case I used the following code for getting the current row:

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.

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

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

回答9:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)    
{

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

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

}

回答10:

 GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);                    
                    HiddenField hdMeasurementId = ((HiddenField)row.FindControl("hdMeasurementId"));

回答11:

GridViewCommandEventArgs not supported row so use naming container to find the control..

  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       Control ctrl = e.CommandSource as Control;  
       if (ctrl != null)
       {
           GridViewRow gvRow = ctrl.Parent.NamingContainer as GridViewRow; 
           Label slno = (Label)gvRow.FindControl("slno");  // Find Your Control here
           TextBox txtno = (TextBox)gvRow.FindControl("txtno");  // Find Your Control here
           // Your work start here
       }
    }
