RadGrid Insert, Update, Delete events not firing

Posted by Community Admin on 03-Nov-2010 00:00

I have created a custom module (using JobsModule as a guide) and have successfully installed and configured it. The module page extends SimpleView.

I am working on developing some functionality using a RadGrid. The page loads fine. I am able put the grid into insert mode using:

protected void AddButton_Command(object sender, CommandEventArgs e)

EmployeesGrid.MasterTableView.InsertItem();

This displays a simple insert form in the RadGrid but when I submit the form the InsertCommand handler does not get called. Here is my InitializeControls code:

protected override void InitializeControls(GenericContainer container)

this.EmployeesGrid.NeedDataSource += new GridNeedDataSourceEventHandler(EmployeesGrid_NeedDataSource);

this.EmployeesGrid.ItemDataBound += new GridItemEventHandler(EmployeesGrid_ItemDataBound);

this.EmployeesGrid.InsertCommand += new GridCommandEventHandler(EmployeesGrid_InsertCommand);

this.EmployeesGrid.UpdateCommand += new GridCommandEventHandler(EmployeesGrid_UpdateCommand);

this.EmployeesGrid.DeleteCommand += new GridCommandEventHandler(EmployeesGrid_DeleteCommand);

this.AddButton.Command += new CommandEventHandler(AddButton_Command);

And my getter for the RadGrid:

private RadGrid employeesGrid;

protected virtual RadGrid EmployeesGrid

get

if (employeesGrid == null)

employeesGrid = base.Container.GetControl<RadGrid>("EmployeesGrid", true);

return employeesGrid;

And my ASCX code:

<telerik:RadGrid id="EmployeesGrid" AllowSorting="true" PageSize="20" AllowPaging="true"

AllowMultiRowSelection="false" runat="server" Gridlines="None"

AutoGenerateColumns="False" Width="97%" ShowStatusBar="True">

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView AutoGenerateColumns="False" Summary="Employees">

<CommandItemSettings AddNewRecordText="Add Photo" RefreshText="Refresh"

ShowAddNewRecordButton="true" ShowRefreshButton="true" />

<Columns>

[...]

</Columns>

<EditFormSettings>

<EditColumn ButtonType="ImageButton" />

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

I did not include my command handler code since the code is not even getting called.

Thanks in advance for your help.

Hello Bryan,

There are issues with the RadGrid control commands in Sitefinity 4.0 BETA and BETA2 release. Please take a look at this post for more detailed information.

Does this apply to GridView and DataGrid controls too?

Hello Bryan,

There should not be an issue if you use GridView control

sample

<asp:GridView runat="server" ID="GridView1" allowpaging="true" PageSize="10" autogeneratecolumns="false" AutoGenerateDeleteButton="True" >

<columns>

<asp:buttonfield buttontype="Link" commandname="Add" text="Add"/>

<asp:boundfield datafield="_title" headertext="title"/>

<asp:boundfield datafield="_name" headertext="name"/>

</columns>

</asp:GridView>

cs

public partial class ButtonControl : System.Web.UI.UserControl

protected void Page_Load(object sender, EventArgs e)

GridView1.RowCommand += new GridViewCommandEventHandler(GridView1_RowCommand);

GridView1.RowDeleting += new GridViewDeleteEventHandler(GridView1_RowDeleting);

GridView1.DataSource = GetDataSource();

GridView1.DataBind();

void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)

public IList<TestSource> GetDataSource()

var list = new List<TestSource>();

for (int i=0; i < 100; i++)

var s = "name" + i;

var t = "title" + i;

list.Add(new TestSource(t, s));

return list;

public class TestSource

public TestSource(string title, string name)

_title = title;

_name = name;

public string _title

get;

set;

public string _name

get;

set;

Hello,

The problem with the RadGrid is not fixed in the RC. The problem is not in the RadGrid control and it comes from our code. Unfortunately we have to fix this in our code and there is no workaround t the issues. I will try to escalate the issue with higher priority so it will get included in the next build.

16/01/2011 This is still the case in final version - This is a MAJOR problem.

Hello CRanaboldo,

The issue still occurs if you bind the control on the server. If you use client side binding and WCF there should not be a problem to subscribe for the events.

Dear Ivan

Thanks, I understand, when will server side be fixed? Do you have an example of the approach that you suggested - client side binding and WCF - for me to use as a template

Many thanks

Charles

Hello,

Here is a a link that shows how to bind the RadGrid to WCF. This links shows how to bind the control with client side binding.

If you want to bind the content items you can use ItemsGrid control.

Hello,

When will the issue of not registering insert, update and cancel events commands be fixed in Sitefinity 4.0?
Thanks!

Hello,

We started working on this and we made progress, but we will need some more time. It turns out that the problem is also related to the ViewState and it will require to change some basics. I hope that we will manage to provide a fix within the next few weeks with one of our internal builds.

Best wishes,

I am having this issue in the 2011 Q1 release. I am just evaluating the quality Telerik so am not familiar with the controls. Is this issue fixed? Hopefully it is just something I am doing. I have used the markup and code from the demo site in my own project but still get the issue.

Any feedback would be appreciated.

Posted by Community Admin on 28-Mar-2011 00:00

Hello Ian,

the problem you are talking about is going to be fixed in 2011 Q1 release of Sitefinity, which is due to be released on April 13th. The issue is not related to Telerik RadControls for ASP.NET Ajax, but rather to Sitefinity.

We have resolved the issue already and we are now in the process of testing the implementation.

Hi all,

the new SF version 4.1 is rolled out, but as I can see, the problem with firing updates of grids within a sitefinity application is not solved.

I built a user control with a simple table that performs inserts, updates and deletes. - After then I integrated it into the toolbox as widget. - It appears at the page, you can do sort and so on, but NO update ......

To check if I would be wrong I made an empty webform outside of sitefinity, linked my user control into this test page and: it updates !!!!! Surprise !!!

So does anybody know why this does not perform in SF projects ?????

Regards, Robert

Did you change the layouttemplatename and layouttemplatepath + add virtual paths according to slavo's post?
If not, you are still using the old sitefinity parser
