How to set a DataKeyValue on Client-side?

Hello,

I am using the Client event 'OnRowSelected' of a RadGrid

I can read the value of a key on client-side using :

function Grid1_Select(sender, eventArgs) {

alert(eventArgs.getDataKeyValue('Param1'));

}

But is there a way to set a new value for this Param1 on client-side?

Regards,

frank Quinty

[Solved] Separate Page for each tab

Because I use a tabstrip I have alot of radControls on my page. This slows down the perfomance extremly, especialy on slower machines. It seems to be the overhead each server controls added client side.

Because of that I had the idea to use a separate aspx page for each tab. Now the question is can I accomplish this the the radTabstrip with build in functionality (I see a PostPackUrl property but its only for whole tabstrip and not for each tab available) oder what is required to do that?

Limitation with Rad Grid grouping

Hi,

I heard that there is a limitation with Rad Grid grouping when the header text of the column bound to the grid has a white space in it. For Eg: If the header text of a particular column is "Company Name", then on dragging the column header to perform grouping, an error was thrown. Reason is, it is grouping the column with name "Company" instead of "Company Name".
I raised a forum earlier also regarding the same. I got reply that this was the limitation with Rad Grid and will be solved soon.
Was this problem solved in any of the latest release for Rad Controls?

Thanks,
Nataraj

Getting Datakeys of selected edit row

HI,

I have a datagrid that is using a custom user control for insert/edit. When the user clicks 'edit' on a row I want to pass the Id datakey into my user control so that I can use it to do a db lookup. I'm sure it can be done but can't figure out how. Can anyone provide me with a solution?

Thanks!

NEW BUG?

I have a RadCalendar Control in one of my columns and the EditMode set to "InPlace".

On the CommandItemTemplate when the "InitInsert" event fires, javascript returns an error:

Line: 6
Char: 62099
Error: Sys.WebForms.PageRequestManagerServerErrorException: Specified Cast Not Valid.
Code: 0

If I remove the Calendar, the Init fires fine.

Any ideas?
Thanks,
Joshua

[Solved] OnColumnCreating event

Anyone using this event?

I saw it from an example at
http://www.telerik.com/community/code-library/aspnet-ajax/grid/adding-custom-column-dynamically.aspx
For adding columns dynamically.

I need to provide editing for a PivotTable-like data structure.
I will have varying columns and rows, and I wanted to provide a grid full of textboxes for the user to do mass edit.
I'll iterate through the rows and columns to do a save on a button click.

The problem is, in my grid, the debugger never hits on the ColumnCreating event.
It will only hit on the ColumnCreated event.

here is the grid definition.

    
                                                    <telerik:RadGrid ID="gridEvil" runat="server" GridLines="None" OnColumnCreating="gridEvil_ColumnCreating">  
        
                                                        <MasterTableView> 
        
                                                            <RowIndicatorColumn> 
        
                                                                <HeaderStyle Width="20px"></HeaderStyle> 
        
                                                            </RowIndicatorColumn> 
        
                                                            <ExpandCollapseColumn> 
        
                                                                <HeaderStyle Width="20px"></HeaderStyle> 
        
                                                            </ExpandCollapseColumn> 
        
                                                        </MasterTableView> 
        
                                                        <FilterMenu EnableTheming="True">  
        
                                                            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
                                                        </FilterMenu> 
        
                                                    </telerik:RadGrid>

It's pretty basic. Please note that I get the same result with or without the OnColumnCreating="gridEvil_ColumnCreating" in the declaration

It also does not matter if I define the signature of the sub with or without Handles gridEvil.ColumnCreating

Do I have to do something special to get this event to fire?

DetailTable expand is very slow

Hi,

The DetailTableBind is very slow..Actually we are using Dynamic databinding for a hierachial RadGrid.
The Hierarchy levels are dynamically created.

Whne i try to click the Plus sign it takes some time to display the child records.We chedk by loading just 2 records to even several thousand records..Both takes the same amount of time to open the child tables.

Any suggesstions on improving the performance of the RadGrid

Thanks
Bala

Invalid ItemIndex when handling OnCommand Event on both server and client sides

I'm using Telerik RadControls for ASP.NET AJAX 2008 Q2 and ASP.net 3.5.

I use a GridButtonColumn to do something on call back to server and it works just fine. The problem arises when I try to do something on the client side when I click the ButtonColumn. After adding the the client side handler, e.Item.ItemIndex will always be set to zero on the server. It only occurs when the CommandName is "View", but "RowClick" works as expected. The problem does not depend on what the client side handler does and an empty client side handler also causes this effect.

Am I doing anything wrong or is there a workaround?

The grid:

    
                                        <telerik:RadGrid ID="GridMessages" runat="server" OnItemCommand="GridMessages_ItemCommand"> 
        
                                            <MasterTableView AutoGenerateColumns="False" DataKeyNames="ID"> 
        
                                                <Columns> ...

                                                    <telerik:GridButtonColumn CommandName="View" ImageUrl="Images/view.gif" ButtonType="ImageButton" 
        
                                                        DataTextField="ID" UniqueName="view"> 
        
                                                        <HeaderStyle Width="16px" /> 
        
                                                    </telerik:GridButtonColumn> 
        
                                                </Columns> 
        
                                            </MasterTableView> 
        
                                            <ClientSettings EnablePostBackOnRowClick="true"> 
        
                                                <ClientEvents OnCommand="GridMessages_Command" /> 
        
                                                <Selecting AllowRowSelect="True" /> 
        
                                            </ClientSettings> 
        
                                        </telerik:RadGrid>

The server side code:

    
                protected void GridMessages_ItemCommand(object source, GridCommandEventArgs e) 
        
                { 
        
                    if (!(e.Item is GridDataItem)) 
        
                        return; 
        
                    e.Item.Selected = true; 
        
                    var id = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"].ToString(); 
        
                    // ... 
        
                    // Load the selected message from database 
        
                    switch (e.CommandName) 
        
                    { 
        
                        case "RowClick": 
        
                            // Preview the message 

                            break; 
        
                        case "View": 
        
                            // Open message in a new tab
        
                            break; 
        
                    } 
        
            }

The client side code:

    
                function GridMessages_Command(sender, args) 
        
                { 
        
                    // Sets the selected page view of a multipage 
        
                }

Thanks,
Ilia
