Hi All,

I have a Grid call MainGrid in the aspx page. In this Grid iam adding one more Grid as ChildGrid and finding the ChildGrid in the ItemCreate event of the MainGrid and binding the childGrid in the same ItemCreatedevent using the DataSource Property. This Child Grid is added to the Tab PageView.

Here it is getting binded, but the problem is ItemCreated Event is getting called many items and i have many records, so the rendering of the grid is very slow.

Can any one help me out, is there any other soloution where i can bind my child grid items

Regards
Asra

Grid and TextBox.

Hello Telerik,

I have a textbox on whose keyup event i m filling the grid.
I have successfully implemented this search.
the grid has 4 columns, "Edit" , "Name", "Town", "Delete".
The problem i am facing is, When i type the item to be searched in textbox, if no such item is present then i Click on "Add New Record" to add that.

Here i have got stuck.

I want that on Clicking "Add new Record" whatever text was there in textbox it should come in "Name" textbox which is opened in Grid for inserting purpose.

So , can you help me how to get it.

Thanks,

Chinmay Sharma.

Grid row background colour confliction

I have a grid with the Web20 skin and client side selection enabled. So when a user clicks on a row it changes the background to a green colour.

I also have logic to change the colour of the row background to red when the status column is 'requested' or 'verified'.

The problem is the skin's green colour is overshadowed by the red when you select a row that already has a colour:

http://img165.imageshack.us/img165/8959/statusgridbd1.jpg

I want to know if there is a property I can use to override the style so users can still see the selection they've made if the background already has a colour, maybe by having a different colour to that green to show they've selected a row that has a colour.

Built-in command handling in ItemCommand

If I create a CommandItemTemplate in a grid that includes commands that otherwise have handler functionality built into the grid itself (e.g. the Rebind command below):

CommandItemTemplate>

div align="right">

asp:LinkButton Style="vertical-align: bottom" ID="ClearButton" runat="server"

CommandName="Clear" Text="Clear"></asp:LinkButton> |

asp:Button runat="server" CommandName="Rebind" CssClass="rgRefresh"/>

asp:LinkButton Style="vertical-align: bottom" runat="server" CommandName="Rebind" Text="Refresh"></asp:LinkButton>

div>

CommandItemTemplate>

how do I prevent my ItemCommand handler from intercepting the default handler functionality in RadGrid being called?

protected void LogGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "Clear")

{

// here I handle my custom Clear command which works fine
return;

}

// but how do I prevent the RadGrid's Rebind command handling from being lost?? I've made various attempts here with RaiseBubbleEvent with no success. Strangely it's only the Rebind functionality that's never called. Commands outside the CommandItemTemplate hitting this function (like DeleteCommand at the row level) still have their functionality carried out by RadGrid.

}

Thanks in advance for any pointers.

Rounded corners

Hey guys!

I need to create round corners for menu tabs using CSS no images.
Found a solution how to do it here, as per example four, nifty tabs:
http://www.html.it/articoli/niftycube/index.html

The question I've got is how do I integrate it with a custom skin.
They are pointing to a tag in this manner:
Nifty("ul#nav a","small transparent top");

I've tried various combinations of using RadMenu_Bannered,
rmFocused, rmRootGroup but it doesn't seem to be doing it for me ;-((

Please help!!

Adding columns in page_init but getting Multiple Controls With The Same ID

Hi,

I'm using RadControls for ASP.NET AJAX Q1 2009

I have a radgrid using NeedDataSource to bind to a dynamicallyt created datasource, depending on columns the user has selected. The grid is created in page_init as recommended to me.

I dynamically create the grid columns myself. One fo these columns is a template column containing a radeditor. I was advised to create columns, especially templated columns, in page_init. When I do this though, I get

Multiple controls with the same ID 'FilterTextBox_tblT1Devices.Name' were found. FindControl requires that controls have unique IDs.

If I create the columns in page load I don't get this message but my template column will disappear after postback as expected, because it's viewstate is not saved.

Another issue is my dynamically created dropdown columns are completely blank no matter what way I configure them. I have had problems with them for days. I'm hoping their problem might be related.

Please advise.

Linux/Windows - Modifications?

Hello!

We are delighted with RadControls-Trial-Testing and we plan to develop a cross-OS web-application (IIS/Apache-Mono).

Is it possible to run RadControls (ASP.NET Ajax) on Linux and Windows without making changes? – I mean, do we have to make changes, like swap the DLL or make business-code modifications, if we deploy on Linux/windows?

Best Regards

Martin, Austria

DropDownList populated based on value in parent grid

This is the situation.

I have a grid with a two level hierachy. In the child grid I have a dropdowncolumn defined. The values for the dropdown come from a business object that returns a List<IServer>. The GetServerList method of the BLL takes a parameter (int environmentID) to ensure only the servers for a particular environment are returned. The environmentID is held on the parent table and can I assume be accessed using the following notation.

e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex][

"EnvironmentID"]

my problem is that I cannot for the life of me work out how to populate the drop down. If it didnt require any parameters then I would simply set it to an objectdatasource defined on the page (as I have for other dropdown columns.)

This must be possible, I have tried stuff in the ItemDataBound/ItemCreated events but just cant seem to get it working.

Someone must have done this before. Any help would be much appreciated.

Regards

Ben Blackmore.

'Sys.WebForms.PageRequestManager' is null or not an object

Hi,

I am getting the above error on my page load.
I am using RadAjaxPanel and RadScriptManager in my page. I browsed for it on net and seems it essentially occurs when a page has UpdatePanel.
I was using inbulit server of Visual Studio for my application till date. I never got this error in development environment but my client is getting error "System.WebForm.PageRequestManagerParsorErrorException" intermittently on staging which I think is originated from this one.
Today, I set up IIS for my application and created virtual directory for it, and this error started occurring always on page load.
(I have already added entry for Telerik.Web.UI.WebResource.axd in HttpHandlers section of my web.config)

I have already read "Eilon Lipton's Blog" and is of no use for me.

My scenario:
I have a grid which has a link in header having name "Add New". When user clicks on this link, new row gets added in the grid. I have RadDatePicker control in one of the columns in my grid. I am Ajaxifying my grid for this functionality.

Various things I tried from blogs are:

1. EnableEventValidation="false" in page directive
2.EnablePartialRendering="true" and LoadScriptsBeforeUI="true" in asp:ScriptManager.

Please help me in this if you have any idea.

Thanks and Regards,
Mangesh Gurav
