HI,
I have a DataTable with Customer Data. I'm binding rad grid dynamically, because upton 3rd column, datatable has static columns after that from 4th columns all columns are Dynamic, so for that I've designed rad grid in dynamic binding and also binded column with Edit and Delete buttons. But the rad grid control item command event is not firing. Below is my code
void BindsGrid(int pageIndex = 0)
       {
 
           SetupTableService pgs = new SetupTableService();
           DataTable dt = pgs.ExportFuelGrade(SupplierId);
           int i = 0;
           if (gvFuelsGrades.MasterTableView.Columns.Count > 0)
           {
               gvFuelsGrades.MasterTableView.Columns.Clear();
               gvFuelsGrades.DataSource = null;
               gvFuelsGrades.DataBind();
                
           }
           foreach (DataColumn col in dt.Columns)
           {
               GridBoundColumn boundCol = new GridBoundColumn();
               string column = string.Format("{0}", dt.Columns[i].ColumnName);
               boundCol.DataField = column;
               boundCol.HeaderText = column;
               // templateCol.UniqueName = column.Replace(" ", string.Empty);
               gvFuelsGrades.MasterTableView.DataKeyNames = new string[] { "FuelId" };
               boundCol.ItemStyle.Width = Unit.Pixel(500);
               boundCol.ItemStyle.Wrap = true;
               if (boundCol.HeaderText == "FuelId" || boundCol.HeaderText == "OilGrade" || boundCol.HeaderText == "FuelGradeId" || boundCol.HeaderText == "ProductGroupId")
                   boundCol.Visible = false;
               gvFuelsGrades.MasterTableView.Columns.Add(boundCol);
                
               i++;
           }
            
           gvFuelsGrades.ClientIDMode = System.Web.UI.ClientIDMode.Static;
           gvFuelsGrades.CurrentPageIndex = pageIndex;
            
           gvFuelsGrades.AllowPaging = true;
           gvFuelsGrades.Width = Unit.Pixel(1000);
           gvFuelsGrades.DataSource = dt;
           gvFuelsGrades.DataBind();
            
            
           //(gvFuelsGrades.MasterTableView.GetColumn("Actions") as GridTemplateColumn).OrderIndex = gvFuelsGrades.Columns.Count+1;
           GridTemplateColumn templateCol = new GridTemplateColumn();
           templateCol.ItemTemplate = new GridActionTemplate("Actions");
           templateCol.HeaderText = "Actions";
           templateCol.OrderIndex = gvFuelsGrades.Columns.Count + 2;
           gvFuelsGrades.MasterTableView.Columns.Add(templateCol);
           gvFuelsGrades.Rebind();
           //(gvFuelsGrades.MasterTableView.GetColumn("Actions") as GridTemplateColumn).Visible = CanEdit() | CanDelete();
       }


and ITemplate Class
class GridActionTemplate : ITemplate
  {
      public event CommandEventHandler Command;
      private void OnCommand(CommandEventArgs e)
      {
          if (Command != null)
          {
              Command(this, e);
          }
 
      }
      private void imgEdit_Command(object sender, GridCommandEventArgs e)
      {
          OnCommand(e);
      }
      public void InstantiateIn(System.Web.UI.Control container)
      {
          lControl = new LiteralControl();
          lControl.ID = "lControl";
          imgEdit = new ImageButton();
          imgEdit.CommandName = "edit";
          imgEdit.ID = "btnEdit";
          imgEdit.ImageUrl = "~/Static/Images/Actions/edit.png";
           
 
          imgDelete = new ImageButton();
          imgDelete.CommandName = "delete";
          imgDelete.ImageUrl = "~/Static/Images/Actions/delete.gif";
           
          Table tbl = new Table();
          TableRow tr = new TableRow();
          TableCell td = new TableCell();
          td.Controls.Add(imgEdit);
          tr.Cells.Add(td);
          td = new TableCell();
          td.Controls.Add(imgDelete);
          tr.Cells.Add(td);
          tbl.Rows.Add(tr);
          container.Controls.Add(imgEdit);
          container.Controls.Add(imgDelete);
      }
      
      protected LiteralControl lControl;
      protected ImageButton imgEdit;
      protected ImageButton imgDelete;
      protected ImageButton imgView;
      private string colname;
      public GridActionTemplate(string cName)
      {
          colname = cName;
      }
  }

Help me in this regards  with making my rad grid fire item command.

Hello Phaneendra,

Could you please try commenting the following line and let me know if the issue still persists:
//gvFuelsGrades.ClientIDMode = System.Web.UI.ClientIDMode.Static;
Microsoft recommends using ClientIDMode=Static only for static control. RadControls on the other hand are controls with complex hierarchies of child controls and templates so setting their ClientID mode to static will break their functionality.
Also I am sending you a simple example, based on your code. Please check it out and let me know if it helps you.

Hello Phaneendra,

Currently, RadGrid does not support changing the orientation of header cells text. However
here are some options which may be helpful:
1. Use the writing-mode CSS property, but it works only in IE.
http://www.css3.com/css-writing-mode/
2. Set HeaderText by letters, not by words, so that the letters can wrap like this:

H
e
a
d
e
r
T
e
x
t

3. Use GridTemplateColumns with images in the HeaderTemplate. The images will contain the flipped vertical text.

Also you could check out the following links:

I hope this helps.
