Referencing a GridDropDownColumn from server-side on postback

Hi All

I have a RadGrid as follows:

<telerik:RadGrid ID="trgStudAttend" runat="server" AllowSorting="True"

AutoGenerateColumns="False" GridLines="None" Skin="Windows7"

CellSpacing="0" AllowMultiRowEdit="True">

<ClientSettings EnableRowHoverStyle="true" />

<MasterTableView DataKeyNames="atdID" EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn DataField="atdID" HeaderText="ID" Visible="false"

UniqueName="atdID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="studDisplayName" HeaderText="Name"

UniqueName="studDisplayName" ReadOnly="True">

</telerik:GridBoundColumn>

<telerik:GridDropDownColumn DataSourceID="sdsTimeOfDayCodes" HeaderText="Time of Day"

ListTextField="comb" ListValueField="todcCode" UniqueName="todcCode" DataField="atdTimeOfDayCode">

</telerik:GridDropDownColumn>

<telerik:GridDropDownColumn DataSourceID="sdsReasonCodes" HeaderText="Reason"

ListTextField="comb" ListValueField="rfacCode" UniqueName="rfacCode" DataField="atdReasonCode">

</telerik:GridDropDownColumn>

<telerik:GridBoundColumn DataField="atdComment" HeaderText="Comment"

UniqueName="atdComment">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

At post back, every item is in edit mode.

I also have a button on my page (trbSave). When clicked, I want to loop through each row in my RadGrid, and determine what the selected value is for my drop down columns. I am trying this so far without any luck:

' Declarations

Dim sqlString As String = ""

Dim sqlCom As SqlCommand

Dim todcDDL As RadComboBox

' Loop through each student in the radgrid, and save the selected values to the details database

For Each i As GridDataItem In trgStudAttend.EditItems

todcDDL = i.FindControl("todcCode"

Next

i.FindControl("todcCode") always returns 'nothing'. Does anyone know how I can reference that drop downlist and get its currently selected value?

403 Forbidden when user click "Add to dictionary" in RadEditor

Hi,

We are using the RadEditor on our sharepoint portal.

When the user tries to add a word to the dictionary a pop-up appears with the following error message: "Spell Checker Handler Server Error: 403 FORBIDDEN".

I presume that adding a word to the dictionary updates one of the *.tdf file. Is there specific security settings to be assigned to those files ?

Data Binding

Does the ASP.Net Ajax grid have options for data binding like the grid in MVC? If not, is it to be expected in an upcoming release?

With the grid in MVC, you have the option of doing the following types of binding:

Server
Ajax/JSON
Web Services

Drag and Drop between Grids

Hi -

I have a page with two RadGrids. Each grid has drag and drop enabled. I use the row-drag capability to re-order items within each grid. The RowDrop event is used on the server side to re-order. It works great. However, I dont want to be able to drag a row from one grid onto the other grid. Is there a way to prevent draging rows from one grid and dropping them on the other on the client? If not, is there a way to determine what the "source" grid was in the RowDrop event on the server. The GridDragDropEventArgs class has a DestinationGrid property in it but no SourceGrid property. Is there a way to determine the source grid so I can just ignore any drops from other grids?

Thanks for your help... Russ

RenderSelectedPageOnly question

Hi, we're using RenderSelectedPageOnly and AutoPostback to load on demand several page views. But now every time we change the selected tab an AJAX request is made (because of the AutoPostback), even though the tab had already been loaded.

We would like to load on demand the selected tab only if it's the first time the user selects that tab. Otherwise the tab change should behave without the AJAX request, just like it would with RenderSelectedPageOnly=false

Is there a way to achieve this behavior?

Best regards,
Santiago.
