Checkbox selection issue wih server-side grid

Hello,

When I am using check box in a server-side grid to select all rows, It selects only the rows in the first page. Why it is not selecting the other pages in the Rad Grid?

Thank You

Request to have some 'NoAddNewButton' in CommandItemSettings + other request

Hello,

Since start of RadControls for Ajax.net, this has not been improved, I don't know why.
It seems we still have to work in codebehind to say I don't want the Add New button, but want the command Item without using a template necessitating a large rework (not skin support in CommandItemTemplate, etc) , isn't it ?

More on command item: the various ShowExportToxxxButton are not recognised by intellisence(certainly a missing declaration) but this is not a show stopper.
What I woul expect would be to be able to write code like this:

    
            <CommandItemSettings  RefreshText="<%$ Resources:ADNCRM,ORDER_VIEW_REFRESH %>"   
        
                                        ShowExportToExcelButton='<%# (ShouldExport2XL) %>' />

but Visual Studio states that this kind of binding is not ok for radGrid ?

Last point, we should not have to add again 2 lines of javascript to fix that these Export buttons should not generate a callback but a real postback. Telerik has everything to do this in background.

My pages are full of these 2 or 3 javascript patch, very uneasy to maintain!
Eliminating all these small 'logical' patches would be a target for Telerik.

Product is good but has to be improved for existing features also.

Regards

Getting values from a grid column that is not visible

Hello,

I need to get the cell value of a grid column that I have set to false. When I make it visible true, I am getting the values. I am using the client side script to get the value when clicking the check box in the grid.

The below is the javascript function I use to ge the value

    
            function getGridCheckedValues(){   
        
               var grid = $find("<%=RadGrid1.ClientID %>");   
        
               var MasterTable = grid.get_masterTableView();   
        
               var selectedRows = MasterTable.get_selectedItems();   
        
              for (var i = 0; i < selectedRows.length; i++){  
        
              var row = selectedRows[i];   
        
              var cell = MasterTable.getCellByColumnUniqueName(row, "fld_id");  
        
              alert(cell.innerHTML);   
        
              }  
        
            }

This is the code I use in the HTML. Please note the column "fld_id".

Is this a bug or am I confused!!!

I am using the grid to dispaly different photo albums. When the ComboBox album selector changes and with ViewState of the Grid enabled, the handler for the OnSelectedIndexChanged event for the ComboBox calls the Rebind() method of the grid to force the grid to rebind which eventually results in the OnNeedDataSource being called to allow the data source for the grid to be updated.

It appears that the Grid.CurrentPageIndex is not being reset to zero when the Grid is rebound. So if this index was anything other than 0 when the Rebind() method was called, an attempt to load the grid with the page index of the previous state of the grid will result.

Since ViewState is enabled, an argument could be made that the CurrentPageIndex is just being persisted due to the persistence resulting from ViewState. But is there really ever a valid case where the paging index should be anything other than 0 after the Grid is rebound.

To me new data implies a new state with indexes reset to zero. If for some reason someone wants an index other than zero when the grid rebinds, then it would seem to be up to them to set the index to whatever they wanted.

I have a feeling that this is not going to go my way. No big deal, this is a very, very good product.

Blank page when printing RadWindow using Custom Button in IE 8

Greetings!

We were getting a blank page (nothing except headers and footers) when printing the contents of a RadWindow (for ASP.Net Ajax) using a Custom Button (according to the KB article: "Adding a Custom Button to RadWindow Titlebar") in IE 8. Adding the following meta tag to the page referenced by the RadWindow solved the problem:

    
            <meta http-equiv="X-UA-Compatible" content="IE=7" />

Insert the tag after the DOCTYPE declaration and just before the HTML Head section.

The tag forces IE 8 to render the page in IE 7 compatibility mode. We didn't experience this phenomenon when using other browsers. Not sure exactly what caused IE 8 to print a blank first page. So, please post a reply if you've experienced this and found an alternative solution.

Hope this saves you time!

ImageButton in grid

hi

I have a grid that display images using image button: I want to be able to retrieve the ID and a response.redirect when click. This is my code:

    
            <ItemTemplate> 
        
                            <asp:ImageButton ID="ImageButton1" runat="server"   
        
                                ImageUrl="~/image/first.png" /> 
        
                            <br />&nbsp;&nbsp;&nbsp;  
        
                            <asp:Label ID="BranchLabel" Width="150px" runat="server"   
        
                                Text='<%# Eval("Branch") %>' /> 
        
                            <br /> 
        
                            <br /> 
        
                        </ItemTemplate>

My Code Behind:

    
            Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
            Dim imagebutton As ImageButton = TryCast(Page.Master.FindControl("RadGrid1"), ImageButton)  
        
            End Sub

CheckBox causing problem in ScrollBar

Hi Support.

Before you directly jump to find the solution, please understand the issue first and also know that I've already spent some time trying to fix it myself.

Here is the problem.

I've a simple RadGrid placed on the form that loads around 3000 rows, with no virtual scroll, no grouping, no hi-fi setting.. Simple RadGrid.
Now, as soon as I place a CheckBox column, or a ClientSelectColumn or a TemplateColumn with a CheckBox, I see unnecessary Vertical ScrollBar showing up on my PAGE NOT the RADGRID.

Below is the html to to generate the radgrid. Note that the RadGrid is placed inside the RadAjaxPanel with Rad

Why RadGrid does'nt supports databinding expressions

Hello,

Why using expressions like

<CommandItemSettings

RefreshText="<%$ Resources:ADNCRM,ORDER_VIEW_REFRESH %>"

ShowExportToExcelButton='<%# (ShouldExport2XL) %>' />

is not possible in VS2008 for Radgrid (Error message in design mode)
I know we could do it in code behind but the price is writing lot of code.

Thanks
