I am using the RadSkinManager on the Masterpage. I have attempted to set a smaller font-size and I've even tried the "!important" settings extension, but the resizing fails to work. The only way I was able to make it work was to completely remove the Telerik style from the control. Thank you in advance for help guidance.

Multiple FormDecorators

I am having a an issue which I figured out I could perhaps work my way around by using 2 FormDecorators - but that doesn't seem to work.

Is it supposed to work with multiple FormDecorators on a page?

This is what my code looks like :

    
              <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" Skin="Black" DecoratedControls="Buttons" /> 
        
              <telerik:RadFormDecorator ID="RadFormDecorator2" runat="server" Skin="Default" DecoratedControls="Textbox" />

How does it look to you?

Custom control in grid refresh page when used

I have a rad grid with a custom control added in the grid whenever a row in the grid is expanded. This control has a radtabstrip control inside and for each radpageview, there are also controls. I have the update panels set in the right spot, at least i think i do. So when i go to use the checkbox or click one of the buttons in the control, the page refreshes and the custom control that was added in the grid is gone. I'm thinking maybe i have my update panels in the wrong spot or i need to do something so that the grid doesn't update when the controls are used. Any help or input on this would be greatly appreciated.

Here's my code for my grid....

    
            <asp:UpdatePanel ID="UpdatePanel5" runat="server" UpdateMode="Conditional" RenderMode="Inline">

Script in RadCodeBlock not found when used in OnClientDoubleClick

Hello,

I want to do some client adaptation on a node doubleclick and I have to customize my script depending language so I used a radcodeblck for it.
But I get an error on Page, the function called by TreeView OnClientDoubleClick is not found .
If I look to page source in browser, the function is here and well formated ?
Here is my code

Delete all rows in a RadGrid with Javascript

Hello.

I need to delete all rows of a datagrid from client side. I have the following javascript code:

******************************************
            var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

            var numRows = masterTable.get_dataItems().length;
            for (i = numRows-1; i >= 0 ; i--)
            {
                masterTable.deleteItem(masterTable.get_dataItems()[i].get_element());
            }

******************************************

In the begining it worked fine, but if I put the radgrid into an updatePanel, it only works for the first row to delete. With the second row, I get this error:

'this.get_element().tBodies' is null or is not an object

I need the radgrid into an update panel in order to perform another tasks server-side using Ajax.

Any idea? Is there another way to delete all rows in a radgrid client-side?

Thanks in advance.

RadGrid not entering in edit mode.

Hi, I'm using RadGrid to show my data.
I programmatically assign the DataSource to the DataGrid
And I'm using almost only TemplateColumn.
And I'm using the EditFormTemplate to define the template for editing (because I need flexibility).
But now, the Grid is not entering in edit mode... I tried a lot of methods.. using CommandName = "Edit" or by using Item.Edit = true or using the EditIndexes Collection... but none of them worked...
Can you help me?
Here the Grid declaration:

    
            <rad:RadGrid ID="articlesGrid" runat="server" AllowPaging="true" AllowSorting="false" 
        
                AutoGenerateColumns="false" AutoGenerateDeleteColumn="false" AutoGenerateEditColumn="false" 
        
                AllowAutomaticDeletes="True" AllowAutomaticInserts="True"  
        
                AllowAutomaticUpdates="True" onitemdatabound="articlesGrid_ItemDataBound"  
        
                onitemcommand="articlesGrid_ItemCommand"  
        
                onsortcommand="articlesGrid_SortCommand" oneditcommand="articlesGrid_EditCommand" 
        
                > 
        
                <MasterTableView NoMasterRecordsText="<%$ Resources:,NoData %>" PageSize="10" AllowPaging="true" AllowSorting="false"> 
        
                    <Columns>

                                    </td> 
        
                                </tr> 
        
                            <!--CONTINUES...--> 
        
                            </table> 
        
                        </FormTemplate> 
        
                    </EditFormSettings> 
        
                </MasterTableView> 
        
            </rad:RadGrid>

Thank you.
PS: I also tried to set the AllowAutomaticDeletes/Inserts/Updates to False but nothing..

How to get filter type/value pair for more than one column filter in custom data load

How can all the filtered types and values from a grid view? In the grid view, we want to provide the flexibility to filter the result by more than one column. We are using custom data source to load the grid. The below URL helps to identify the last selected filter type and value (for example col.5).

http://www.telerik.com/help/aspnet-ajax/grdoperatewithfilterexpression.html

But I’m interested to know ALL the previously selected (for example Col 1, Col 2, and Col 3) filter type and value

I’ve contacted the support and they have not given me the direct (appropriate) answer. Could any one help me?

RadGrid CSS problems. Header and row moved too far to the right.

I am having a problem with my RadGrid control. It appears that the header line, one of the rows and some of the text is shifted all the way over to the right to the point where it's past the right border area. How can I fix that? See the link for a picture. Thanks!

Filtering a column using DataFormatString

I have several columns in a instance of RadGrid using a DataFormatString to display currency with the decimal values removed (i.e. {0:c0}).

When a user attempts to filter on any of these columns using the "Equals" filter option, nothing is returned. I presume this is because the underlying data contains the decimal values which is what RadGrid is filtering on.

Is there a recommended way of handling this scenario?
