Pb selecting an item when binding to datatable

Hello,

I am binding to an arraylist which contains object items with properties 'name' and 'val', when I call DataBind, ComboBo items are successfully created, but I'am unable to select one of the items.
It's so trivial that I'm thinking I have an error somewhere else, here is my code:

It runs in the Page_Load event of my page, not other interaction after.
The radCombo is not ajaxified, no autopostback.

    
                        ArrayList ar                    =   im.CategoryList;  
        
                        RadComboCat.DataSource          =   ar;  
        
                        RadComboCat.DataValueField      =   "val";  
        
                        RadComboCat.DataTextField       =   "name";  
        
                        RadComboCat.DataBind();  
        
                        if ( catId == 0 )  
        
                        {  
        
                            RadComboCat.SelectedIndex   =   0;  
        
                        }  
        
                        else  
        
                        {  
        
                            string strCat               =   catId.ToString();  
        
                            Trace2.WriteLine( string.Format("[V]CRMImageEdit FillCatComboSelected FindItemByValue: [{0}], catId:{1}",strCat,catId),CrmImageTrace.Sw.Info);  
        
                            RadComboBoxItem it          =   RadComboCat.Items.FindItemByValue(strCat);  
        
                            Trace2.WriteLine( string.Format("[V]CRMImageEdit FillCatComboSelected FindItemByValue found : {0}", it != null ),CrmImageTrace.Sw.Info);  
        
                            if (it != null)  
        
                            {  
        
                                it.Selected = true;  
        
                                Trace2.WriteLine( string.Format("[V]CRMImageEdit FillCatCombo Selected Item: {0}, catId:{1}",it.Text,catId),CrmImageTrace.Sw.Info);  
        
                            }  
        
                        }

Trace shows that the it.Selected= true instruction is executed, but when page is displayed, nothing is selected.
When I select from the UI, the value is well selected and I can store it ????
What could be the reason ?

(Hollidays I know....)

Thanks
CS

RadGrid Error with Edit ImageButton

Hi,

I'm having a problem with edit button in the RadGrid. Everything works fine when I use a ButtonType of linkButton, but when I switch the Button type to ImageButton, I get the following error.

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I don't understand why everything works fine with a linkbutton but not with an imagebutton. Does some different event get fired with an ImageButton?

The aspx code is as follows:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="gridTest.aspx.cs" Inherits="<...our path here...>Presentation.Web.UI.InventoryManagement.gridTest" %>

[Solved] Get GridTemplateColumn control client-side

I'm sure someone can quickly point me in the right direction, but I've been tearing my hair out (something I can ill afford to do).

I have a RadGrid with columns arranged
GridTemplateColumn\GridBoundColumn\GridBoundColumn\GridTemplateColumn
Column 1 has an ASP CheckBox, column 4 an ASP DropDownList.

If the checkbox is unchecked, the dropdown is disabled; checking enables the dropdown. That's all good.

I also have a RadContextMenu on the Grid. I would like to enable or disable the menu items dependent on the state of the checkbox. This would need to be client-side JavaScript, within the OnClientItemClicked event (that's where I inspect the Menu item to see what I need to do).

I haven't been able to find anything about how to access a control within a GridTemplateColumn (maybe I've just not been looking in the right place?). I can get at values if I add them to ClientDataKeyNames, but that's not appropriate.

I've managed a workaround using a hidden field, but I'd like the code to simply check the enabled state, for reliability reasons (checking the value of a certain field isn't quite as robust as I'd wish).

Hide a child grid

Hi,

I have a RagGrid with many child grids at the same level and im trying to hide the child grid if it is empty but im running into problems identifying the empty grids

I have tried looking at prerender and detailtable databind then looking at the items in the grid where the item count is 0 then hiding based on this but the grids always have an item count of 0 they always hide the grid even when they have data in them

e.g.

     GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
     foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
     {
       foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
       {
         if (nestedView.Items.Count == 0)
         {

         if (nestedView.Items.Count == 0)
         {
           nestedView.Visible = false;

         }

Any Ideas?

Thanks in advance

[Solved] status bar with rtl

I've just started incorporating RadGrid into my web application.
One of the problems i've incountered (as my previous datagrid exp. was limited to winforms) was that the status bar text does not correpond with the overall direction of the grid (although i've already noticed that i had to set the align in the ItemStyle of each column to right).
After a few interrogations of my own, i've noticed that you encapsulated the text of the status using a span with the style property - float:left.
Thus the status text ignores the overall style.
Is there anything i can do to fix it?
tnx for any reply...
