How to Enable Required Field Validator in Edit Mode not Insert Mode based on another column data

[gc_0620]

Folks,

I have a RadGrid (RadGrid1) with 2 Template coulmns, Unique Name "Fulltime" and  "Division" . I would like to see if RadGrid is in Edit Mode and Value of Column "Fulltime"   = "Yes"  then Required Field Validator ="RequiredFieldValidator1" will be activated else not.
Another way, if RadGrid is in Insert Mode then Column Division is not required but it is in Edit Mode and Column "Fulltime"   = "Yes", then Column Division is required.  I do not see Insert Temple options in Rad Grid. Below is my code.

I am using RadControls for ASP.NET AJAX Q2 2009 NET35 with VS 2008. Any help will be appreciated. Thanks.

Hello gc_0620,

You can hide the validation control if GridTableView.IsItemInserted is false. For more info I suggest you to check this example where we have used similar technique for the command item:

Vlad,

I think you misunderstood me. I want to check:

If Rad Grid is in Insert/Edit Mode. 

1) If Rad Grid is in Insert Mode, Column Division is not required.

2) If Rad grid is in Edit Mode and column  Fulltime   = "Yes",  then dynamically (i.e in Run time) create a RequiredFieldValidator (i.e. RequiredFiledValidator1) for Column Division. 

I mean RequiredFieldValidaor1 will Validate the Control Division only if RadGrid is in Edit Mode and Value of Column Fulltime = "Yes".

I want also to clarify I am using Custom Command Item Templates not inline Edit Command (i.e. not using GridEditCommandColumn). Below is my CommanditemTemplate (similar to : http://demos.telerik.com/aspnet-ajax/grid/examples/programming/commanditem/defaultcs.aspx). Thanks

 <CommandItemTemplate>
                    <div style="padding: 5px 5px;">
                        Custom command item template&nbsp;&nbsp;&nbsp;&nbsp;
                        <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" Visible='<%# RadGrid1.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Edit.gif" />Edit selected</asp:LinkButton>&nbsp;&nbsp;
                        <asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited" Visible='<%# RadGrid1.EditIndexes.Count > 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Update.gif" />Update</asp:LinkButton>&nbsp;&nbsp;
                        <asp:LinkButton ID="btnCancel" runat="server" CommandName="CancelAll" Visible='<%# RadGrid1.EditIndexes.Count > 0 || RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Cancel.gif" />Cancel editing</asp:LinkButton>&nbsp;&nbsp;
                        <asp:LinkButton ID="LinkButton2" runat="server" CommandName="InitInsert" Visible='<%# !RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/AddRecord.gif" />Add new</asp:LinkButton>&nbsp;&nbsp;
                        <asp:LinkButton ID="LinkButton3" runat="server" CommandName="PerformInsert" Visible='<%# RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Insert.gif" /> Add this Customer</asp:LinkButton>&nbsp;&nbsp;
<asp:LinkButton ID="LinkButton1" OnClientClick="javascript:return confirm('Delete all selected customers?')"
runat="server" CommandName="DeleteSelected"><img style="border:0px;vertical-align:middle;" alt="" src="Images/Delete.gif" />Delete selected customers</asp:LinkButton>&nbsp;&nbsp;
                        <asp:LinkButton ID="LinkButton4" runat="server" CommandName="RebindGrid"><img style="border:0px;vertical-align:middle;" alt="" src="Images/Refresh.gif" />Refresh customer list</asp:LinkButton>
                    </div>
                </CommandItemTemplate>

Hi,

Indeed to check if the grid is in insert mode you should use IsItemInserted.


All the best,
