Cannot get a reference to an edited item

I have a RadGrid with an Edit button on the left.

When I click on the Edit button, I simply want to enable/disable some fields.

No matter what I try in the below code-behind, I'm getting a null value from the "editedItem", which then means the rest of the items using the FindControl will also be null.

Can someone please inform me how I can get a reference to the edited item (editedItem)?

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == "Edit")
            {
                if (e.Item is GridDataItem)
                {

                    GridEditableItem editedItem = (source as RadGrid).NamingContainer as GridEditableItem;
                    //GridEditableItem editedItem = e.Item as GridEditableItem;

                    DropDownList FileTypeID = editedItem.FindControl("FileTypeID") as DropDownList;
                    TextBox StartPosition = editedItem.FindControl("StartPosition") as TextBox;
                    TextBox EndPosition = editedItem.FindControl("EndPosition") as TextBox;
                    TextBox Delimiter = editedItem.FindControl("Delimiter") as TextBox;
                    CheckBox IsMultiRecordType = editedItem.FindControl("IsMultiRecordType") as CheckBox;
                    TextBox FirstRecordIndicator = editedItem.FindControl("FirstRecordIndicator") as TextBox;
                    TextBox RecordIndicatorIndex = editedItem.FindControl("RecordIndicatorIndex") as TextBox;

                    if (IsMultiRecordType.Checked == true)
                        FirstRecordIndicator.Enabled = true;
                    else
                    {
                        FirstRecordIndicator.Text = null;
                        FirstRecordIndicator.Enabled = false;
                    }

                    switch (FileTypeID.SelectedItem.Text)
                    {
                        case "Space Fixed Length":
                            StartPosition.Enabled = true;

Telrick control not marking on page

hi,

Our company had corporate account with terick and we have all the terick 2007, 2008, 2009. On the VS 2008 , I crated a pge where I create a multiview collaboration with radtab and page view control. Itw was successful and its all done.

Now later I came back to this page , and wanted to create d another multiview as somewhat same as before. But now when I drag and drop any control from the toolbox nothing happened on the page. Nothing render. I don't know what is going on. I am being really frustrated. I have dont it and now I can't do the same.

Only thing changed is we changed have the new computer but I did install the Terick control on the the new environment. I do have these controls on my toolbox. When I place the 2007 control they do render but nothing for 2007 and 2009.

Just to check what is going on , maybe I have problem with the design surface I tried to directly pace this control on the source code.
Wen I did that I got this message " The operation could not be completed. Invalid FORMATETC structure".

Please help .

RenderSelectedPageOnly Problem?

Hi There,

My tab strip is defined like this

<telerik:RadTabStrip ID="programTabStrip" runat="server" EnableViewState="false" MultiPageID="programMultiPage" AutoPostBack="true" >

<Tabs>

<telerik:RadTab Text="Residents" Selected="true"></telerik:RadTab>

<telerik:RadTab Text="Rotations"></telerik:RadTab>

<telerik:RadTab Text="Approvers"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="programMultiPage" runat="server" RenderSelectedPageOnly="true">

<telerik:RadPageView ID="RadPageView1" runat="server" Selected="true">

<uc2:Residents ID="Residents1" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView2" runat="server">

<uc3:Rotations ID="Rotations1" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView3" runat="server">

<uc1:ProgramApprovers ID="ProgramApprovers1" runat="server" />

</telerik:RadPageView>

</telerik:RadMultiPage>

So in the rotation usercontrol I'm getting an "Object reference not set to an instance of an object." error in NeedsDataSource (of the Radgrid that exists)

...but it only happens after a click event is triggered?

I can get around it by checking for null on sender in the NeedsDataSource...but is this a bug? Actually it's the DataSource property of the RadGrid that's null, not the grid itself

Dynamic radgrid with template columns and "Multiple controls with same ID" error on postback

Hi guys,

Having some trouble with my grid. It's in a web control, dynamically built in Page_Init(). The page loads fine the first time, but on postback I get an exception that there is already a control called 'tbTemplateControl' That name belongs to one of my GridTemplateColumns, FacilityColumn.

#endregion

}

I apologize for the length, but I think that's everything you need to use in a test project.

So I'm creating the grid in Page_Init(), databinding in NeedDataSource(). What else can I try?

Thanks,

RadDatePicker Client Events Not Working After an Ajax Update (Partial Postback)

Hi,

I am new to telerik controls and I have inherited a website that heavily relies on Telerik controls.

I have created 2 raddatepickers. One of them has a client event OnDateSelected that updates the 2nd datepicker with a calculated date based on the first one. This works fine until another control on the same page/panel causes a partial postback (using the RadAjaxManager). After the partial postback my client event can no longer access the raddatepicker client object.

I have set the client event to be reattached after the partial postback. I don't know if that is necessary. ( I assumed it was based on this page http://www.telerik.com/help/aspnet/toolbar/toolbar_clienteventsunattached.html). I know that the event is reattached b/c I have stepped into the code using Firebug. However, when the set_selectedDate function runs nothing happens to the 2nd datepicker.

Here is the code that I used:

<telerik:RadDatePicker ID="dateTetanusReceived" runat="server">

<ClientEvents OnDateSelected="TetanusDateSelected"></ClientEvents>

</telerik:RadDatePicker>

<telerik:RadDatePicker ID="dateTetanus" runat="server">

</telerik:RadDatePicker>

var _TetanusExpiryPicker = $find("<%= dateTetanus.ClientID %>");

var _TetanusPicker = $find("<%= dateTetanusReceived.ClientID %>");

function TetanusDateSelected(sender, e) {

SetSecondDatePicker(_TetanusExpiryPicker, 10, e);

}

function SetSecondDatePicker(datePicker, yearsToAdd, e) {

var expiryDate = e.get_newDate();

expiryDate.setFullYear(expiryDate.getFullYear() + yearsToAdd);

datePicker.set_selectedDate(expiryDate);

}

//Event gets called after a partial postback ends

function OnResponseEndHandler(sender, arguments) {

_TetanusPicker.add_dateSelected(TetanusDateSelected);

}

Any help would be appreciated.
