Button Click not working for the second time.

Hi,

In my aspx page, I got two List view and an add button. I am trying to remove one row from the list view and adding it to another List view. The button click event is working fine for the first time. But not working on the second time.

My settings

<telerik:AjaxSetting AjaxControlID="cmdAdd">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="lv1" /> 
                    <telerik:AjaxUpdatedControl ControlID="lv2" />             
                </UpdatedControls>
</telerik:AjaxSetting>

if I remove the above settings code, the button click event is working fine.

When I checked the generated html on firebug the following click event disappears on second time. Any idea how to fix it? am I missing any settings? Thanks for the help.

onclick="javascript:__doPostBack('ctl00$ContentPlaceHolder1$cmdAdd','')"

RadGrid vs EditMode vs accessing DataItem

Dear Telerik,

I've got a RadGrid, which has been filled with data from EntityDataSource - perfect. First column contains a GridEditCommandColumn, which fires correctly and display a FormTemplate with plenty of TextBoxes, FormTemplate contains also w RadButton with CommandName="Update" (and Cancel) - data updating works perfecty.
One of bound columns is a "Status_ID" column, which is related to another table (MSSQL). Statuses are displayed (inside FormTemplate) with RadTreeView control - also works perfectly. Unfortunately I could not find any solution for "automagical" binding "SelectedValue" of RadTreeView control with some of "Bind(column)" expression, so I've used the "NodeDataBound" event and if node.Value equals my Status_ID I select it.

Unfortunately the problem is, when I'd like to change another node from RadTreeView and fire data updating. Now I'm using such method (just after NodeClick)

var n = (e.Node);

int selectedStatus = int.Parse(e.Node.Value.ToString());

if (Respondent_Current == null)

{

int respondentId = int.Parse((this.RadGrid_Respondent.EditItems[0] as GridDataItem).GetDataKeyValue("ID").ToString());

Respondent_Current = Csi_Entities.PB_Respondent.Where(i => i.ID.Equals(respondentId)).First();

}

if (Respondent_Current != null)

{

Respondent_Current.Status_ID = selectedStatus;

this.Csi_Entities.SaveChanges();

this.RadGrid_Respondent.Rebind();

}

else { //Crap }

Which works, but it's ugly - when I update textboxes AND i update RadTreeView just after and I submit, the textboxes-changes are ignored where status is updated correctly - but it's obvious with my solution.

What would be nice:
1. When node click - update an entity object which is used by FormTemplate (not the new one).
- Maybe I should update data by accessing the (EditItems[0] as GridDataItem).DataItem as MyEntity)? Will it work?
2. On CommandName="Update" fired, all controls might be successfully updated - am I right?

Thank you for ur time & help ;)

All the best,
Przemek M. Zawada

Time interval in radscheduler

In my Radscheduler I am giving 15 minutes interval with MinutesPerRow="15" and the time panel shows time as 8:00 am,8:30 am,9:00 am etc even though there is 15 min interval in between.

How can I show 8:00 am,8:15 am,8:30 am etc in the scheduler time panel so that user can easily distinguish the time interval.

Thanks,
Soumya

RadTreeView not Binding

Hi,

I am trying to bind my RadTreeView control but for some reason the (+) sign is not coming with parent node to expand it and bind child nodes on server side.

Any help would be really appreciated.

Thanks

Set the row colour dependant on checkbox column

Hi,
I am wishing to change the colour of a row if it is 'urgent' in my internal message system.
I found this code...

Protected Sub RadGrid1_ItemDataBound(ByVal sender As System.Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

'Change the color of inactive rows

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim Urgent As CheckBox = DirectCast(item.FindControl("Urgent"), CheckBox)

If Urgent.Checked = True Then

e.Item.BackColor = Drawing.Color.RoyalBlue

End If

End Sub

and changed it to suit my grid, or so I believed; however it does not work properly, and throws an exception ("Object reference not set to an instance of an object.") when checking whether

"If Urgent.Checked = true then"

What am I doing wrong, the code for my radgrid is...

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateSelectColumn="True" CellSpacing="0"

GridLines="Horizontal" AutoGenerateColumns="False" OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged"

RTM-Date for SAK?

Hi,
I have tested SAK in a SharePoint 2010 environment.
Apart from the point that in a list-item edit page when using the RadEditor and inserting Images the image-editor seems to behave a bit strange (i.e. I click resize and nothing happens) and that the image-editor does not fit intor the list-item edit page popup the RadEditor is really nice.
When will SAK be RTM? I'd hate to suggest deploying CTP ;-)

Best,
Nils
