hide item on popup editform

[Mydatafactory]

Hello,

In my grid I have several columns with items. To edit the items I use the popup editform. Some of the items in the grid I want to hide on the popup editform. Although I searched the forum and tried several solutions the problem is still there.

Here's my .aspx code:

	<telerik:RadGrid ID="gvTasksDataSteward" runat="server" AutoGenerateColumns="False"
	DataSourceID="dsTasks" GridLines="None" Skin="Office2007" >
	<ClientSettings EnablePostBackOnRowClick="true">
	<Selecting AllowRowSelect="true" />
	</ClientSettings>
	<MasterTableView DataSourceID="dsTasks" Name="DatastewardTasks" DataKeyNames="TaskId" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" EditMode="PopUp">
	<RowIndicatorColumn Visible="False">
	<HeaderStyle Width="20px"></HeaderStyle>
	</RowIndicatorColumn>
	<ExpandCollapseColumn Visible="False" Resizable="False">
	<HeaderStyle Width="20px"></HeaderStyle>
	</ExpandCollapseColumn>
	<Columns>
	<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandProject" >
	<HeaderStyle Width="20px" />
	</telerik:GridEditCommandColumn>
	<telerik:GridBoundColumn DataField="TaskId" HeaderText="TaskId" UniqueName="TaskId" Visible="false"></telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="CompanyName" HeaderText="Company" SortExpression="Company" UniqueName="Company"></telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="ProjectName" HeaderText="Project" SortExpression="ProjectName" UniqueName="ProjectName"></telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="TaskDescription" HeaderText="TaskDescription"
	SortExpression="TaskDescription" UniqueName="TaskDescription">
	</telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="Remarks" HeaderText="Remarks" SortExpression="Remarks"
	UniqueName="Remarks">
	</telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="StartDate" DataType="System.DateTime" HeaderText="StartDate"
	SortExpression="StartDate" UniqueName="StartDate" DataFormatString="{0:d}">
	</telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="SoortBewerking" HeaderText="SoortBewerking" SortExpression="SoortBewerking"
	UniqueName="SoortBewerking">
	</telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="RealHours" DataType="System.Decimal" HeaderText="RealHours"
	SortExpression="RealHours" UniqueName="RealHours" Visible="false">
	</telerik:GridBoundColumn>
	<telerik:GridBoundColumn DataField="StatusId" UniqueName="StatusId" Visible="false"></telerik:GridBoundColumn>
	<telerik:GridButtonColumn ButtonType="PushButton" UniqueName="Accept" Text="Accept" ImageUrl="~/Images/OK.png" ShowInEditForm="false" CommandName="Accepted"></telerik:GridButtonColumn>
	<telerik:GridButtonColumn ButtonType="PushButton" UniqueName="NotAccept" Text="Not Accept" ImageUrl="~/Images/OK.png" ShowInEditForm="false" CommandName="NotAccepted"></telerik:GridButtonColumn>
	<telerik:GridButtonColumn ButtonType="PushButton" UniqueName="Executed" Text="Executed" ImageUrl="~/images/11new.gif" ShowInEditForm="false" CommandName="Executed" ConfirmText="Executed?"></telerik:GridButtonColumn>
	</Columns>
	<EditFormSettings CaptionFormatString="Edit: {0}" CaptionDataField="ProjectName">
	<PopUpSettings ScrollBars="Auto" ></PopUpSettings>
	<EditColumn ButtonType="ImageButton" CancelText="Cancel Edit" UpdateText="Update Task"
	InsertText="Insert User" UniqueName="EditCommandColumn">
	</EditColumn>
	<FormTableButtonRowStyle HorizontalAlign="Right"></FormTableButtonRowStyle>
	</EditFormSettings>
	</MasterTableView>
	</telerik:RadGrid>

And here's one of the solutions I've tried:

	Protected Sub gvTasksDataSteward_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles gvTasksDataSteward.PreRender                   For Each item As GridDataItem In gvTasksDataSteward.EditItems
	Dim itemToEdit As GridEditableItem = If((item.OwnerTableView.EditMode = GridEditMode.PopUp), DirectCast(item, GridEditableItem), DirectCast(item.EditFormItem, GridEditableItem))
	itemToEdit("StatusId").Visible = False
	Next End sub

Hello,

Editable column have a ReadOnly property that determines whether the column editor is visible in the edit form or not. If you want the column editor does not appear in the edit form you should set a ReadOnly property to True.

Thanks for your reply. Setting the ReadOnly property to True was the solution.

Setting a column to readonly stops it being available on updates using the following code :

if Id is set to readonly it will not be available here :

protected void ScriptConfigGrid_UpdateCommand(object source, GridCommandEventArgs e)
{
    GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item;
    Hashtable ht = new Hashtable();
    gridEditFormItem.ExtractValues(ht);
    string Id = ConvertNullToEmpty(ht["Id"]);

Hi Toby,

One suggestion is to set the id as DatakeyName and can access it in the UpdateCommand.

C#:

protected void ScriptConfigGrid_UpdateCommand(object source, GridCommandEventArgs e)
{
    GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item;
    Hashtable ht = new Hashtable();
    string Id= (e.Item).OwnerTableView.DataKeyValues[e.Item.ItemIndex]["UniqueName"].ToString();   // Get the DataKeyValue
    gridEditFormItem.ExtractValues(ht);
}

Thanks,
Shinu.

thanks for that, for some reason (e.Item).OwnerTableView.DataKeyValues is an empty array, I have added the datakeynames to the grid i.e.

<telerik:RadGrid ID="ScriptConfigGrid" runat="server" Visible="true" AutoGenerateColumns="false"
                               AllowMultiRowSelection="true" PageSize="12" Width="420" AllowPaging="true" DataKeyNames="Id"
                               OnNeedDataSource="ScriptConfigGrid_NeedDataSource"
                               OnUpdateCommand="ScriptConfigGrid_UpdateCommand" OnItemDataBound="ScriptConfigGrid_ItemDataBound"
                               OnInsertCommand="ScriptConfigGrid_InsertCommand" OnDeleteCommand="ScriptConfigGrid_DeleteCommand" >
                               <MasterTableView CommandItemDisplay="Top" EditMode="PopUp">

anything else I need to do?

the datasource is a generic list, which is set in the code on the page_load

thanks

Hi Toby,

Please provide the DataKeyNames to the MasterTableView as shown below.

ASPX:

<telerik:RadGrid ID="ScriptConfigGrid" runat="server" Visible="true" AutoGenerateColumns="false"
                               AllowMultiRowSelection="true" PageSize="12" Width="420" AllowPaging="true"
                               OnNeedDataSource="ScriptConfigGrid_NeedDataSource"
                               OnUpdateCommand="ScriptConfigGrid_UpdateCommand" OnItemDataBound="ScriptConfigGrid_ItemDataBound"
                               OnInsertCommand="ScriptConfigGrid_InsertCommand" OnDeleteCommand="ScriptConfigGrid_DeleteCommand" >
                            <MasterTableView CommandItemDisplay="Top" EditMode="PopUp"  DataKeyNames="Id">

Thanks,
Shinu.
