Hi,

I'm using RadControls for ASP.NET AJAX Q1 2010 with C# (Visual Studio 2008, EPi-Server)
and have some problems with skinning.

I've copied skins from their installed folder of C:\...\RadControls for ASP.NET AJAX Q1 2010\Skins\...
and given them new names in my C# solution - Grid.ProductShortList.css, etc. I've added the accompanying
folders on the same level as the CSS-files, and of course altered the names of the classes, etc. inside the CSS-files.

The CSS-files are referenced either by a masterpage, or in some cases by the page itself.

Since the RadChart only has a "common" CSS, I've used this, and renamed the copy Chart.KraftinorEpi.css.

The problem is that some of the charts that use this skin works, but others don't.
The ones that don't work get a dark gray background (#525252) - sort of a negative/inverted look.

The attached image shows two radcharts (black bars are just censored information),
both existing in the same .ascx file. Both are set to Skin="KraftinorEpi" EnableEmbeddedSkins="false".
The lower chart has the correct look, but the upper chart displays the weird "inverse" look.

Any ideas what the reason for this can be?

Client-side XML databinding

Hello,

I want ask, if is possible use other means of fill data as list of objects? For example DataSet or XML for Client-side databinding. Can I generate XML and then transform to necessary structure for RadGrid?

Both two samples (Client-side databinding) are only with list of objects, but I need something dynamically (XML, DataSet), not objects with defined structure.

Thanks.

$find returns null

Hi,

I am trying to invoke a javascript function on the Pageload event and get the object of the comboox in that function. But the $find returns me a null.
Here is my page load method in .cs file

protected void Page_Load(object sender, EventArgs e)

{

Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("SaveOriginalValues();");
}

This is my javascript function

function SaveOriginalValues()

{

var cmb1 = $find('<%= cmb1.ClientID %>');

var selectedItem = cmbHealthPlan.get_selectedItem();

}

cmb1 has a null value when I execute this.
Could anyone please help?

Thanks & Regards,
Ketaki

Image Button inside RadGrid Template Column

We had an issue with the radconfirm popup which has to open on the click of delete image button which is present in the Telerik Radgrid template column.

Scenario:

Usually we call a callback function and get the argument(Yes/NO) which user has selected.

In the call back function we used to get the reference of the button and then do a post back.

We tried the same approach here also, but since the Image button is inside the template column we are unable to get the reference in Javascript.

Question:

How to get the control id of a Image button which is present in a Telerik RadGrid in Javascript ?

Can you please help us on this

}

itemlast = item;

}

RadChart1.PlotArea.YAxis.AddRange(0, maxr, 1);

Conn.Close();

}

And this is result into attach.

Why this code doesn't work for my case? Why time stamps are cut?

RadChart1.PlotArea.XAxis.Appearance.LabelAppearance.Dimensions.Height = Telerik.Charting.Styles.Unit.Pixel(15);

RadChart1.PlotArea.XAxis.Appearance.LabelAppearance.Dimensions.Width = Telerik.Charting.Styles.Unit.Pixel(150);

Forum web site malfunctioning

Can an admin please delete the posts that I submitted with the title "No InsertItemTemplate in RadGrid?" I don't know why, but, it kept failing when I tried to submit it. I didn't think it went through. So, I changed it and resubmitted it multiple times. Now I see the posts listed in the list, but, if you click on them, the pages don't display.

[Solved] Hide Filter Row When Editing a Record

Group,
I have a RadGrid and I want to be able to hide the row of filters when I am in the OnEditcommand. I can do it using Javascript by selecing radio buttons or clicking a button, but I just want it to automatically hide when in edit mode.

I tried using
gvProductionRuns.AllowFilteringByColumn = !gvProductionRuns.AllowFilteringByColumn;

but it causes issue with what record I am actually updating. I know there has to be an easy solution to this, but I am not finding it.

Any help is greatly appreciated!
