Binding dropdownlist with inplace edit mode error

Hi,

I am trying to bind a dropdownlist in the itemdataBound event, but when I enter edit mode I am getting the error:
"Specified argument was out of the range of valid values. Parameter name: index"
for the line:
"Dim editor As GridDropDownListColumnEditor = CType(editMan.GetColumnEditor("Band"), GridDropDownListColumnEditor)"

I was referring to this to bind the dropdown: http://www.telerik.com/help/aspnet-ajax/grid-customize-configure-griddropdowncolumn.html

Any ideas why I am getting this error?

My code is below:

RadGrid1_ItemDataBound

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

If TypeOf e.Item Is GridDataItem Then

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

Dim row As DataRowView = DirectCast(e.Item.DataItem, DataRowView)

item("Band").Text = row("Band").ToString()

item("capoptioname").Text = row("capoptioname").ToString()

End If

If (TypeOf e.Item Is GridEditableItem AndAlso CType(e.Item, GridEditableItem).IsInEditMode) Then

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim editMan As GridEditManager = editedItem.EditManager

Dim editor As GridDropDownListColumnEditor = CType(editMan.GetColumnEditor("Band"), GridDropDownListColumnEditor)

Dim ddlBand As DropDownList = editor.DropDownListControl

Dim ProductBus As New Product

Dim bands As Entities.Product.callbandsDataTable

bands = ProductBus.GetCallBandsList

ddlBand.DataSource = bands

ddlBand.DataTextField = "description"

ddlBand.DataValueField = "value"

ddlBand.DataBind()

End If

End Sub

Loading is too slow if tabstrip's AutoPostBack is true

Hi,

We are currently having performance problem on the TabStrip when the AutoPostBack property is set to "True" even there is no server side event attached. It takes about 3 seconds to show the newly selected tab. There is no problem if AutoPostBack property is set to "False".

Is there any workaround ?

Regards,

Semih

get_masterTableView() returning null in OnGridCreated event. Used to work before.

I have a client side function that fires when the "OnGridCreated" event is triggered. The code in there used to work fine, then we got an update, now we discover get_masterTableView() is returning null in some cases were it used to be ok. Any idea?

function onGridCreated(sender, eventArgs) {

if (rowIsSelected()) {

.....

function rowIsSelected() {

var getSeletecteRow=getSelectedRow();

......

function getSelectedRow() {

var employeeSummaryGrid = $find('<%=EmployeeSummaryGrid.ClientID%>');

if (employeeSummaryGrid != null)

{

var MasterTable = employeeSummaryGrid.get_masterTableView(); //this is returning null in some cases

return MasterTable.get_selectedItems()[0];

}

return null;

}

HashTable - ClientBinding

Hi.

I would like to display values of a HashTable inside a ClientBinding, is this possible?

If not i would like to recommend it.
It should be possible to declare a container for the hashtable, and inside fields that can display the key and value of the hashtable, for all entries inside the hashtable the key/value pair will get duplicated and filled with there corresposing values till the end is reached.
How can i achieve this functionality when its not already possible?

RadComboBox clearselection issue

Hi,
I have one rad combo box , text box and a submit button at my rad window popup. At the time close popup at 'OnClientClose' i have cleared the rad combo box selection at client side as per below snippet,
var comboDeactivateReasonTruck = $find("<%= cboDeactivateReasonTruck.ClientID %>");
                comboDeactivateReasonTruck.clearSelection();
                comboDeactivateReasonTruck.commitChanges();

but internally the event for that respective combobox is not cleared. So when i trying to click on submit now at that first time if we have any validation message then its working fine ,now we are close that window popup and reopen and click again on submit instead of that submit event combobox event has been fired and nothing is happened. Is there any solution for that..?

Thanks in Advance...
