Column Span an ItemTemplate? Edit mode

[mac]

Trying to get a TemplateColumn to span 3 columns when in edit mode.
Every time it renders in insert or edit, columns 1 and 2 are pushed out. I would like it so the checkbox list can run wild horizontally.  I build my checkbox list at ItemDataBound.

<MasterTableView EditMode="EditForms" AutoGenerateColumns="false" DataKeyNames="PK" CommandItemDisplay="Top">
<EditFormSettings ColumnNumber="3" >
</EditFormSettings>
<columns>
<telerik:GridTemplateColumn UniqueName="Assigned" EditFormColumnIndex="0" HeaderText="Assigned" >
<EditItemTemplate>
<asp:HiddenField ID="HidAssigned" runat="server" Value='<%# Eval("Assigned") %>' />
<asp:CheckBoxList RepeatDirection="Horizontal" ID="CBAssigned" Runat="server" />
</EditItemTemplate>
<ItemTemplate>
<%#Eval("Assigned") %>
</ItemTemplate>
</telerik:GridTemplateColumn>

Hi Mac,

Thank you for contacting us.

I tried to reproduce the described issue, but to no avail. I am sending you a simple example based on your code. Please check it out and let me know what differs in your case.

Looking forward for your reply.

Kind regards,

Hi Radoslav
if you expand your sample to add a couple more columns than just the two on column 0 then the issue is easily recreated.
your sample expanded:
ADD:

 

 

<telerik:GridBoundColumn EditFormColumnIndex="1" HeaderText="Col2" DataField="Col2" />

 

 

 

<telerik:GridBoundColumn EditFormColumnIndex="2" HeaderText="Col3" DataField="Col3" />

 

 

 

void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

 

 

{

 

 

 

DataTable table = new DataTable();

 

 

table.Columns.Add(

 

"PK");

 

 

table.Columns.Add(

 

"Col2"); //added

 

table.Columns.Add(

 

"Col3"); //added

 

table.Columns.Add(

 

"Assigned", typeof(Boolean));

 

 

 

 

for (int i = 1; i < 8; i++)

 

 

{

 

table.Rows.Add(i,

 

true);

 

 

}

 

RadGrid1.DataSource = table;

 

}

 

}

Once you enter Edit mode, you will see that columns 1 and 2 are now pushed out to the end of column 0 checkboxlist. I would like to somehow merge cells 0,1,2 on the checkboxlist row.

Hi Mac,

To achieve the desired functionality you could try setting the RadGrid.MasterTableView.TableLayout property to Fixed and set explicitly the Widths to the RadGrid, MasterTableView and the columns' HeaderStyle:

<telerik:RadGrid runat="server" Width="1130px" AutoGenerateEditColumn="true" ID="RadGrid1">
        <MasterTableView EditMode="EditForms" Width="1130px" TableLayout="Fixed" AutoGenerateColumns="false" DataKeyNames="PK"
            CommandItemDisplay="Top">
            <EditFormSettings ColumnNumber="3">
            </EditFormSettings>
            <Columns>
                <telerik:GridBoundColumn DataField="PK" HeaderText="PK">
                <HeaderStyle Width="100px" />
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn UniqueName="Assigned" EditFormColumnIndex="0" HeaderText="Assigned">
                <HeaderStyle Width="800px" />
                    <EditItemTemplate>
                        <asp:HiddenField ID="HidAssigned" runat="server" Value='<%# Eval("Assigned") %>' />
                        <asp:CheckBoxList RepeatDirection="Horizontal" ID="CBAssigned" runat="server" />
                    </EditItemTemplate>
                    <ItemTemplate>
                        <%#Eval("Assigned") %>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridBoundColumn EditFormColumnIndex="1" HeaderText="Col2" DataField="Col2" ><HeaderStyle Width="100px" /></telerik:GridBoundColumn>
                <telerik:GridBoundColumn EditFormColumnIndex="2" HeaderText="Col3" DataField="Col3" ><HeaderStyle Width="100px" /></telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

Additionally I am sending you the modified version of the example.
