Accessing Controls in Insert Form

[Marlayna]

Inside my RadGrid Edit Form I have a checkbox that toggles other fields in the form Enabled property. Following advice posted in another thread involving using the OnItenDataBound and OnPreRender, I am able to accomplish this with no issues when in edit mode; however, the control collections are empty when in insert mode.

protected void Grid_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
     GridEditableItem item = e.Item as GridEditableItem;
     CheckBox cb = (CheckBox)item["Toggler"].Controls[0];
     cb.AutoPostBack = true;
  }
}

protected void Grid_PreRender(object sender, System.EventArgs e)
{
   foreach (GridEditFormItem item in rgrdList.MasterTableView.GetItems(GridItemType.EditFormItem))
   {
     if (item.IsInEditMode)
     {
        bool isToggled = ((CheckBox)item["Toggler"].Controls[0]).Checked;
        ((TextBox)item["TextItem1"].Controls[0]).Enabled = isToggled;
        ((TextBox)item["TextItem2"].Controls[0]).Enabled = isToggled;
        ((TextBox)item["TextItem3"].Controls[0]).Enabled = isToggled;
     }
   }
}

What am I missing? Any suggestions would be greatly appreciated.

Thank you,

Hi Marlayna,

Try accessing the controls in Insert mode as shown below.

CS:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if((e.Item is GridEditFormInsertItem)&&(e.Item.OwnerTableView.IsItemInserted))
        {
         GridEditFormInsertItem item = e.Item as GridEditFormInsertItem;
         CheckBox cb = (CheckBox)item["Toggler"].Controls[0];
         cb.AutoPostBack = true;
        }
    }

Thanks
Shinu.

Hi Shinu,

Thank you, I tried it and no go. Item["Toggler"]'s control collection is still empty. Could it be that I am working with a really old version of the RadGrid(3.1.1.0)? If so, is there a hot fix I can use? I am constrained in being able to upgrade to the lastest.

Thank you,

Hi,

Have you set the proper ColumnUniqueName in the aspx? Sending your aspx will be more good.

Hi Shinu,

Yes, I have set the columns UniqueName properties. Below is my aspx snippet of the RadGrid and the OnInit event handler. As you can see, I am dynamically creating the columns from an xml file in the OnInit. I have no other issues except that the control collection is empty when inserting.

The aspx snippet:

	<rad:RadGrid ID="rgrdList" runat="server" EnableAJAX="true" EnableAsyncRequests="true"  AutoGenerateColumns="false"
	OnInit="rgrdList_Init" OnNeedDataSource="rgrdList_NeedDataSource" OnPreRender="rgrdList_PreRender"
	OnItemDataBound="rgrdList_ItemDataBound" OnItemCommand="rgrdList_ItemCommand"
	OnInsertCommand="rgrdList_InsertCommand" OnUpdateCommand="rgrdList_UpdateCommand" OnDeleteCommand="rgrdList_DeleteCommand"
	Width="1000px" Height="800px">
	<MasterTableView AutoGenerateColumns="false" EditMode="EditForms" CommandItemDisplay="Top" ShowHeadersWhenNoRecords="true" >
	<CommandItemTemplate>
	<span><asp:LinkButton ID="btnInsert" runat="server" CommandName="InitInsert" Text="Add New Record" /></span>
	<span style="margin-left:50px;"><asp:LinkButton ID="btnSave" runat="server" CommandName="Save" Text="Save All Changes" /></span>
	<rad:RadWindowManager ID="RadWindowManager1" runat="server">
	<Windows>
	<rad:RadWindow ID="RadWindow1" runat="server" Title="List Management - Validation Failed" NavigateUrl="ListErrorMessage.aspx" Height="515px" Width="525" VisibleOnPageLoad="false" />
	</Windows>
	</rad:RadWindowManager>
	</CommandItemTemplate>
	</MasterTableView>
	<ClientSettings>
	<Resizing AllowColumnResize="True" EnableRealTimeResize="True" ResizeGridOnColumnResize="True"></Resizing>
	<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" ScrollHeight="500px"></Scrolling>
	<Selecting AllowRowSelect="True"></Selecting>
	</ClientSettings>
	</rad:RadGrid>

The OnInit handler:

	protected void rgrdList_Init(object sender, EventArgs e)
	{
	if (ListFile == null) return;
	rgrdList.MasterTableView.Columns.Clear();
	GridBoundColumn col = new GridBoundColumn();
	col.UniqueName = "RowIndex";
	col.DataField = "RowIndex";
	//some formatting & added GridTextBoxColumnEditor
	rgrdList.MasterTableView.Columns.Add(col);
	GridEditCommandColumn ecol = new GridEditCommandColumn();
	ecol.EditText = "Edit";
	ecol.InsertText = "Insert";
	//some formatting
	rgrdList.MasterTableView.Columns.Add(ecol);
	XmlNode node = ListFile.SelectSingleNode("Grid/GridModel");
	GridCheckBoxColumn ccol = new GridCheckBoxColumn();
	ccol.UniqueName = "Toggler";
	ccol.DataField = "Toggler";
	//some formatting & added GridCheckBoxColumnEditor
	rgrdList.MasterTableView.Columns.Add(ccol);
	foreach (XmlNode item in node.ChildNodes)
	{
	if (item.Attributes["Title"] != null && !item.Attributes["Title"].Value.Equals(""))
	{
	col = new GridBoundColumn();
	col.UniqueName = item.Name;
	col.DataField = item.Name;
	//some formatting & added GridTextBoxColumnEditor
	rgrdList.MasterTableView.Columns.Add(col);
	}
	}
	GridButtonColumn bcol = new GridButtonColumn();
	bcol.UniqueName = "btnDelete";
	bcol.ButtonType = GridButtonColumnType.LinkButton;
	bcol.Text = "Delete";
	bcol.CommandName = "Delete";
	bcol.ConfirmText = "Are you sure you want to delete this record?";
	//some formatting
	rgrdList.MasterTableView.Columns.Add(bcol);
	}

Thank you,

Hi,

Try adding the columns to the column collection first and then set its properties in the PageLoad event.

CS:

private void Page_Load(object sender, System.EventArgs e)
{
 if ( !IsPostBack )
 {
   GridBoundColumn boundColumn;

   //Important: first Add column to the collection
   boundColumn = new GridBoundColumn();
   this.RadGrid1.MasterTableView.Columns.Add(boundColumn);

   //Then set properties
   boundColumn.DataField = "CustomerID";
   boundColumn.HeaderText = "CustomerID";
   boundColumn.UniqueName= "CustomerID";
 }

Thanks
Shinu.
