I have the following code for a radgrid. When i click on Add a little form comes up and when i fill it out and click insert, i am trying to loop through the form values but i don't know what exactly i should loop or how. Because its not really a form collection. Any help is very much appreciated.


protected void Page_Load(object sender, EventArgs e)
        {
            if (Session["GridData"] == null)
            {
                DataTable table = GetTable();
                Session.Add("GridData", table);
            }
            DefineGridStructure();
        }
     
     
        private void DefineGridStructure()
        {
            RadGrid grid = new RadGrid();
            grid.ID = "RadGrid1";
            grid.NeedDataSource += new GridNeedDataSourceEventHandler(grid_NeedDataSource);
            grid.AutoGenerateEditColumn = true;
            grid.AutoGenerateDeleteColumn = true;
            grid.AllowAutomaticInserts = true;
            grid.Width = Unit.Percentage(100);
            grid.PageSize = 15;
            grid.AllowPaging = true;
            grid.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;
            grid.AutoGenerateColumns = false;
            grid.MasterTableView.Width = Unit.Percentage(100);
            grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.TopAndBottom;
            grid.AllowAutomaticDeletes = true;
            grid.AllowAutomaticUpdates = true;
            grid.InsertCommand +=grid_InsertCommand;
            grid.MasterTableView.DataKeyNames = new string[] { "RowNumber" };
            GridBoundColumn boundColumn = new GridBoundColumn();
            boundColumn.DataField = "RowNumber";
            boundColumn.HeaderText = "RowNumber";
            boundColumn.ReadOnly = true;
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Size";
            boundColumn.HeaderText = "Size";
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Description";
            boundColumn.HeaderText = "Description";
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Quantity";
            boundColumn.HeaderText = "Quantity";
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Duration";
            boundColumn.HeaderText = "Duration";
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();

            boundColumn.HeaderText = "DurationType";
            grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Amount";
            boundColumn.HeaderText = "Amount";
            grid.MasterTableView.Columns.Add(boundColumn);
            PlaceHolder1.Controls.Add(grid);
        }
     
        private void grid_InsertCommand(object sender, GridCommandEventArgs e)
        {
            // Looking to loop through the form so i can insert the values into the datatable
        }
     
         
     
     
     
        void grid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            DataTable current = (DataTable)Session["GridData"];
            RadGrid grid = (RadGrid)sender;
            grid.DataSource = current;
     
        }
     
     
     
        static DataTable GetTable()
        {
            //
            // Here we create a DataTable with a few columns.
            //
            // Create Datatable to store all colums
            DataTable dt = new DataTable();
            DataRow dr = null;
            dt.Columns.Add(new DataColumn("RowNumber", typeof(string)));
            dt.Columns.Add(new DataColumn("Size", typeof(string)));
            dt.Columns.Add(new DataColumn("Description", typeof(string)));
            dt.Columns.Add(new DataColumn("Quantity", typeof(string)));
            dt.Columns.Add(new DataColumn("Unit", typeof(string)));

            dt.Columns.Add(new DataColumn("DurationType", typeof(string)));
            dt.Columns.Add(new DataColumn("Amount", typeof(string)));

Hi Brad,

I guess you want to access the textbox values in the insert mode.Please try the following code snippet.

C#:
private void grid_InsertCommand(object sender, GridCommandEventArgs e)
   {          
       try
       {
            GridEditableItem insertitem= (GridEditableItem)e.Item; 
           TextBox txt1 = (TextBox)insertitem["Size"].Controls[0];
           string size = txt1.Text; //Value of size //
           TextBox txt2 = (TextBox)insertitem["Description"].Controls[0];
           string description = txt2.Text; //Value of description
           //Similarly other columns          
       }
       catch (Exception ex)
       {  }  
   }


Thanks,
Princy
