Hi,
I am able to create and bind columns at run time into radgrid. But when I click "Edit" link for any record, error message is displayed like this.

Please find below the code for ASP page and C# page.

Thanks,
Chocks

Hi,

For most of the grids in our project, there are more than 35 columns,to minimize the time taken to load the grid, we are trying to use the gridpersister to save the settings for individual user, so that the user can customize the number of columns they want to see everytime.
Saving the grid setting data works fine. While loading the settings data in grid, the column header and data gets wrapped  or clipped and sometimes some of the columns which is supposed to be visible are hidden and sometimes we cannot scroll to the end of grid and some columns at the end are clipped.

Below is the grid definition:

Any of these wrapping or clipping problem happens if any one of the column is unchecked from the Header Context Menu, if we check all the visible columns and save the settings, the grid alignment comes back to normal.

Thanks.

Hi,
I need a controller for select special hour in a day. I need it to select special time in a day to send an SMS. Can I use Scheduler control?
If yes: how? Current Data-time is not necessary. Scheduler shows the 24 hours and exist checkbox in each hour to check special hour.

IHello,

I am trying to insert a preslected set of values into a table (Activity)  trough the check box list. however I am getting nothing inserted. I have got 3 tables which are.     Job,      |        Activity,                |  ActivityDetails
                                            ========================================
                                                              |        JobId                   |
                                                              |       ActivityDetailIdI     |

the preselected values are coming from the ActivityDetails table (5 values).

I am folling the example from the demo." Control Insert with ToolTip"

Thanks I have done it

Hi everyone

First of all, I'm aware of another existing thread that has the almost same title; I've read it, and it didn't solve my problem; therefore I decided to write a new thread.

My problem goes as follows:

I have an UpdatePanel placed in a page, which is defined as follows:

I need the Label and the Label's type to invoke some JavaScript with the ScriptManager.RegisterStartupScript method, which we will see later; both the UpdatePanel and Label are only needed for this purpose, and the RadComboBox is not placed in there!

The following is the JavaScript method I need to invoke using the ScriptManager.RegisterStartupScript:

And the following is the RegisterStartupScript method I use in the code-behind file:

Everytime the JavaScript method gets invoked by the RegisterStartupScript method from the code-behind, I get the following error on the client-side:

Uncaught TypeError: Cannot call method 'get_text' of null

The RadComboBox can't be found on the client-side using $find in this special situation. If I try to access it from Chrome's JS Console using the $find method, I'll get the object, and the invocation of a method on it works perfectly. 

What am I doing wrong here? How can I fix this? It's a pretty annoying little problem, and I hope somebody can point me to the right direction.

Thanks very much in advance guys!

I have a RadGrid with the property UseStaticHeaders = true for freezing the header row while scrolling.
but when i set this property to true Width of Headers does not match the corresponding Column Header Width while setting that property to false keeps headers and columns width match. How can i have frozen headers matching columns width?

After being unable to resolve this issue with my own code, I tried running the demo site in IE7. To my surprise, it has the same issue.

Steps to Recreate

1. Go to: http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/filtering/defaultcs.aspx
2. Filter by shipped date: enter a date or use the date picker, click on the associated filter icon
3. View the results...

Hi,

We have a hyperlink in the radgrid and unfortunately the filtering doesn't work.
The following ASPX code have been used:

<telerik:GridHyperLinkColumn HeaderText = "Discussion Name" DataTextField="Discussion_Name"
ItemStyle-HorizontalAlign="Left" UniqueName="Discussion_Name"
DataNavigateUrlFields="Discussion_Id" SortExpression="Discussion_Name" ItemStyle-Width="320"
DataNavigateUrlFormatString="Observation.aspx?Id={0}">
</telerik:GridHyperLinkColumn>

Any ideas why is this?

Thanks!
