        lblerror2.Text = "";
        //((label)gv.Rows.FindControl("lbl1")).Text;

        string str = gv_imageslist.c

        if (str  == "Status")
        {
            status = ((Label)gv_imageslist.Rows[e.RowIndex].FindControl("lbl_Status")).Text;
            Gm.Gallery_Id = Convert.ToInt32(gv_imageslist.DataKeys[e.RowIndex].Value.ToString());
            if (status == "True")
            {
                Gm.Is_Active = false;

            sts = ((Label)gv_imageslist.Rows[e.RowIndex].FindControl("lbl_Cover")).Text;
            Gm.Gallery_Id = Convert.ToInt32(gv_imageslist.DataKeys[e.RowIndex].Value.ToString());

            string sp = ((Label)gv_imageslist.Rows[e.RowIndex].FindControl("lbl_category_Id")).Text;
            Gm.Category_Id = Convert.ToInt32 (sp);

Answer 1

试试这个代码片段；

gv.HeaderRow.Cells[i].Text

Answer 2

Why not create an object of the selected row and work with it from there?

ie

var selectedRow = (TYPE)gridViewName.GetFocusedRow();

You could then use the selectedRow object and call any properties belonging to it ie var name = selectedRow.Name

Answer 3

It can be possible through DataKeyNames and Normal method also

1) 'e' as Commandargument

int index = Convert.ToInt32(e.CommandArgument); string request = gvRequests.Rows[index].Cells[4].Text.ToString();

2) GridViewRow selectedRow = gvRequests.Rows[index]; string Id = gvRequests.DataKeys[index].Value.ToString().Trim();

string headerText=gvProductList.HeaderRow.Cells[1].Text;

protected void gvCustomers_RowDataBound(object sender, GridViewRowEventArgs e)

{

if ((e.Row.RowType == DataControlRowType.DataRow))

{
   LinkButton lnk = (LinkButton) e.Row.FindControl("lnk");
   Label lblName= (Label) e.Row.FindControl("lblName");                      
   lnk.Attributes.Add("onclick", "getValue(" + lblName.ClientID + ");"
}

}... You can try this... method in your own way

Enjoy... ..
