Hello all,

On my page I have a list of employees on the left side of the page, and as the user selects different employees I want to change the colors of the employee selected in the bar chart that I have.

In the attached you will see 2 bar charts, the chart I am talking about is the "Branch Sales Compparision" chart. The chart that shows multiple employees.

So in the attachment I have choosen Ian F. Jones so in the bar chart I want to make his bar colors a darker color.
Thanks,
KS

Different DataTypes in one Templatecolumn

Hi there,

I have to handel different Datatypes in one Templatecolumn. For this I have to load dynamic different controls to provide a proper interface for the user.
I attached a picture to this post.

As you can see, the column "typ" represents different kinds of datatypes. If the user presses the editbutton, the control in the colum "Wert" has to represent a proper control. For the date-type I need the "raddatepicker" and for the integer a RadNumericTextBox and so on.

Anybody an idea to solve this problem?

Best regards.

RadGrid Not Sorting

This is very complicated, but I will try and explain. I have a RadGrid that contains a Repeater inside a GridTemplateColumn. The repeater is a usercontrol that I've written, that is a HyperLink with some javascript that accommodates an onmouseover effect.

I have many records in my database that use this display. For most of them, I have no problems and the entire interface works as expected. There is one record (at least that we've discovered so far) that gives me this bizarre problem: the page loads just fine and displays as expected, but when I click on a column to sort I get a "The connection was reset" error. I have played around with this a bunch and have discovered that if I set the HyperLink in my usercontrol that is inside the repeater to "#" instead of a valid URL, the page works as expected. If I set the URL to some long (but valid) URL (http://www.telerik.com/community/forums/new-thread.aspx?forumId=249, for example), the sorting behavior fails.

Note: this problem ONLY occurs with this specific record - all other records that we have tested with exhibit the expected behavior. And because setting the HyperLink NavigateUrl to a valid URL with appropriate characters also causes this unexpected behavior, it is clearly not an issue with our data.

So I think the problem might have to do with the ViewState size. Are there any known issues related to ViewState size and RadGrid sorting?

If necessary, if you give me a direct email address, I can give you the URL and login information to the staging site for you to reproduce the problem. As I'm sure you understand, I don't want to post that information on a public forum.

Thank you,

Rachael

GridSettingsPersister doesn't correctly load PageSize with customer pager

I noticed that when using GridSettingsPersister.LoadSettings, it does not load the PageSize into the RadGrid when I am using a custom pager. I was able to fix this for myself by change the below method of GridSettingsPersister. Is this a correct fix?

    protected virtual void LoadPagingSettings()
    {
        if (Grid.MasterTableView.AllowPaging && Settings.PageSize > 0)
        {
            //Grid.MasterTableView.PageSize = Settings.PageSize;
            Grid.PageSize = Settings.PageSize;
        }
    }

Thanks!
