ConfirmText for a grid button column in RadGrid

Hi,

I want to add value for ConfirmText in run time. I have a ragdrid and gridbuttoncolumns. Of that first column is an image button and rest are some data from the db. On clicking that button in the grid, we can set a confirmtext in design time. But I need the text to be set during runtime in my C# code. Is that possible?

Thanks.

Custom Validation for radgrid

I have a unique reqiuremnt for validation.

I have 2 bound fields and a calculated fiels that is the difference of the 2 bound fields.
if the difference is not zero than the user must add a comment (a third bound field). The validation must make sure something is in the comment field. If the difference is zero the comment is optional

I am using a custom validator and i a correctly entering it. I guess what i need is a javascript function that will return me the value of a calculated field

Thanks in advance, john

Getting a Gridcolumn in a RadGrid to be hidden

Hello everyone,

Here is what i am trying to do.

I am trying to hide a Gridcolumn in a RadGrid.

I have found the code to do it... i just don't seem to get it to fire when i am first loading the Grid.

Here is my setup

Radtabstrip (6 tabs) with RadMultipage with 6 RadPageviews
each tab(views) has a RadGrid in it. Each one of the grids has a maximum amount of columns that can be displayed and i have a check box control that limits what is displayed.

I have the code that iterates through the checkboxlist and hides the columns... I just cannot get this code to fire when the page first loads...

Where should i be putting this code in (right now it is in the checkboxlist selecteditem changed event... which is good ... but i also need this filtering done on first page load.

Thanks for any ideas...

Corey

Command item Template

In your examples you use a special SessionDataSource and asp:AccessDataSource on the asp page. At our installation we do not place datasources on the asp page - they are usually implemented as typed/non-typed datasets stored in a session variable that are bound to the grid in the grid_NeedDataSource event: grid.DataSource = DataTable;
What do I need to do for Command item Template model to work as it does in your example?

[Solved] RadGrid - Clientside Filter by RadComboBox

Hi,

my problem is that i want to filter clientside.

Within tabs i use the RadGrid - Control.

To Filter clientside i define in the RadGrid

a <ClientSettings> Section and
a the MasterTAbleView - Attribute "DataKeyNames"

But when i go through the Records the Statement:
(Triggert by RadComboBox OnClientSelectedIndexChanged)

DataItems[i].getDataKeyValue("DataKeyName")

is always null.

Here the Code snippets

Change position of leaf node image

I'm adding an image to a leaf node in code-behind like this:

    
            rNode.ImageUrl = "images/icon_navflag.gif"

This works fine. Now, I'd like to move the position of the image to the left about 50px within the treeview. How can I do it?

[Solved] Button doesn't get to RadGrid1_ItemCommand

Hi There,

Here is my 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 have a button within my RadGrid. The button is supposed to fire the event RadGrid1_ItemCommand but it doesn't even get there. Instead I get that error. I have a RadScriptManager on my masterpage so I can add another one. I've tried EnableEventValidation="true" I've tried to even add it to the web.config but I keep receiving this error.

Any help would be appreciated thanks.

edit: Incase it matters. The Button carries the RecordId as an Argument which I want to use in code. If it got there.
