The issue is I have some dropdownlists on the grid that map to enumerations.  In each one of these drop down lists, the first choice is always blank - nothing there at all. 

I'm using an objectdatasource with this.

When I use inplace editing or the form that's built for me using template columns, I can select blank and udpate the database with null - not a problem.

However, when I try to use the Template edit mode, I get an error raised in the RaisePostbackEvent method.  It complains that cannot convert a string (the blank in the dropdownlist) to the enumerated type. 

This is going on in the objectdatasource I know, but I'm asking here because you guys seem to be solving this issue someway in non-template editing form mode, or maybe I'm missing something ??? 

Side note: The business object that's being bound exposes 4 different types of enumerated datatypes. They're all nullable types.  I also have logic in the set accessor to handle empty string data that comes in.  However, it appears the ObjectDataSource is doing its own thing creating the object and not using my set accessors. 

Wondering if it's possible to actually grab the business object itself before it creates it and change the fields.  I was able to extract it the objectdatasource's updating event, but that fires after it's already created. 

It's annoying and I dont' understand why it doesn't work in template edit mode. 

Here's the grid:

Hi community,

I had a simple question. Is it possible to retrieve a RadComboBox control (or any other control)
from the <EditItemTemplate> of a GridTemplateColumn when the Grid is
NOT in Edit Mode?


Or To Explain Further if necessary:

The issue is that I am importing from an excel spreadsheet into a grid. One of the grids
has a <GridTemplateColumn> with a Label control in the <ItemTemplate>
and a RadComboBox in the <EditItemTempalte>. The 'DataTextField' of the combo
box is something like 'product_name', the 'DataValueField' is something like 'product_id'.

code:

 

<telerik:GridTemplateColumn HeaderText="Product" UniqueName="prodDropDown">

 

<EditItemTemplate>

 

<telerik:RadComboBox ID="prodDropDown"

 

DataSourceId="prodDataSource"

 

DataTextField="prod_name"

 

DataValueField="prod_id"

 

Visible="true" runat="server" />

 

</EditItemTemplate>

 

<ItemTemplate>

 

 

 

<asp:Label ID="prodDropDownLbl" runat="server" Text='<%# Eval("prod_name") %>'></asp:Label>

 

</ItemTemplate>

 

</telerik:GridTemplateColumn>

 

 

The problem is that the user only knows the 'product_name' values so that's what they put
in the spreadsheet.

After they do the import, a grid appears with all the data (for review purposes) along with a 'Commit To Database' button.
I am using 'GridTemplateColumn ' because I am trying to display the value of 'Product' to the user as just a 'Label' as opposed to a 'RadComboBox' control.

The problem is I need to get at the <EditItemTemplate> part to set the product_id after the Excel is imported.
So far I haven't been able to get the combo box control unless the grid is in edit mode.

If anybody could help, it would be appreciated. Thanks!

i have a RadComboBox and some TextBoxes in a UserControl that i use this UserControl as UserControlEditFrom in a Radgrid ,
when i go to edit mode from grid i need to bind the my combo box to own current value from DataBase,
in same cases about text boxes i use this code (like your example here : http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx ) to bind text property of my text box :

<asp:TextBox Text=<%# DataBinder.Eval( Container, "DataItem.Title" ) %> ID="TextBoxTitle" runat="server"></asp:TextBox>

but about my combo box !!!!!!!!!!! what shoud i do ?

i search your example (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx ) but you dont use any line of code to bind combo but it work when i test your sample by editing different row of grid !!!!!!!!
what you do ? and what does it work ?

it is a part of your code front of your project that i think in the bold line you should have use anything to bind combo like textboxes :

<tr>
                    <td>Birth Date:</td>
                    <td>
<asp:TextBox id="TextBox11" runat="server"
Text='<%# DataBinder.Eval( Container, "DataItem.BirthDate") %>'
                         tabIndex=4>
                        </asp:textbox></td>
                </tr>
                <tr>
                    <td>Title Of Courtesy</td>
                    <td>
                        <asp:dropdownlist id="ddlTOC" runat="server" tabindex="7"></asp:dropdownlist></td>
                </tr>
            </table>
        </td>
        <td>

I just want to show the RadAjaxLoadingPanel with client side and not used AJAX , just like a loop in javascript, I have tried the follows method, but did not worked.


Does the RadAjaxLoadingPanel support this ? or only can used with AJAX ?

Thanks!

Dear telerik,

We notice some differences when we enable SaveScrollPosition and AllowKeyBoardNavigation between IE8 and Chrome (RadGrid Version Q12009).

We were able to isolate the problem in a single grid defined as follows in a default.aspx page:

1) Open the above page in IE 8
2) Start scrolling using the keyboard down arrow.
    It works fine till the active row reaches the last visible line in the grid (in this case Customer ID=CACTU)
3) Press the down arrow again, the active row changes, but the grid does not scroll. I.e. the active row remains hidden (Why?)
4) Press the down arrow 5 more times till you active the Customer=DUMON (you have to manually move the vertical scroll bar to view the active row)
5) Make sure the active row is not the last visible row
6) Press the Post Back button, the grid will reposition itself exactly where it was, i.e. the SaveScrollPosition works under IE (Correct).

Now, lets repeat the same under Chrome (latest version)

1) Open the above page in Google Chrome
2) Start scrolling using the keyboard down arrow.
    It works fine till the active row reaches the last visible line in the grid (in this case Customer ID=CACTU)
3) Press the down arrow again, the active row changes, and the grid scrolls fine making the active row visible (Correct)
4) Press the down arrow 5 more times till you active the Customer=DUMON
5) Make sure the active row is not the last visible row (by moving the vertical scroll bar)
6) Press the Post Back button, the grid will reposition itself but without respecting the scroll postion placing the last active row CustomerID=DUMON as the last visible row, i.e. the SaveScrollPosition does not work under Chrome (Why?).

Please help us solve this bug.

Hi All,

I've tried it all as per the forums and demos but,..??  I just can't get the RadAjaxManager's  AjaxRequest ex the RadWindow's onclientclose event to fire.
Any ideas, have i missed something dumb??
Telerik version is 2009.1 


I have

<

 

telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"

 

 

onajaxrequest="RadAjaxManager1_AjaxRequest"

 

 

Style="position: relative"

 

 

DefaultLoadingPanelID="RadAjaxLoadingPanel1">

 

 

<AjaxSettings>

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

</AjaxSettings>

 

 

</telerik:RadAjaxManager>

The aspNavPanel (the updated control) is an ASP panel inside a radsplitter which wraps my Navigation RadPane and it's dbound radmenu.
The javascript is ( within the Body of the form.)

 

 

<telerik:RadCodeBlock ID="radcodeblock1" runat="server">
<script language="javascript" type="text/javascript">

 

 

 

 

 

 

 

 

    function OnClientClose()

 

    {

        $find(

"<%=RadAjaxManager1.ClientID%>").ajaxRequest();

 

 

    } ; 

 

 

    function Login()

 

    {

 

        if (<%= Show %> == true)

 

        {

 

            var urlExtn = "ms=" + new Date().getTime();

 

 

            var oWnd = radopen("Forms/Auth/Login.aspx?" + urlExtn , "Login");

 

            oWnd.add_close(OnClientClose);

        }

    };

 

 

</script>

 

 

</telerik:RadCodeBlock>

i have tried this as well

{

    BindMenu();

}

Hello

i use from rad 2008 Q2

my grid code is
aspx

but row indicator not shown

thanks
Ali

This is probably something very simple, but I seem to be missing it.

  I have a master page that defines the RadAjaxManager and RadAjaxLoadingPanel.  My detail page employs a RadAjaxManagerProxy that does not specify the loading panel.  However, since it's just a proxy, the proper loading panel, defined in the master, is shown. 
  On this same detail page I have a dynamically loaded user control.  In that user control I have defined another RadAjaxManagerProxy to ajaxify the controls within that user control.  The ajax seems to working nicely, but the loading panel does not appear.  Is there some reason for this? 
  I manually created another loading panel wihin the user control and specified it within the RadAjaxManagerProxy, but that didn't show either.

Hi

I want to create a rad tree view programmtically in cs file, add the desired nodes to it programmatically, and then extract the HTML string  being rendered on the page in cs file.

And then use this html furher in my code.

I tried  using RenderControl to htmltextwriter, but it says that page is not available.


Kindly help.
