Hi!
                We have
a version of the Telerik AJAX controls from a few years ago, 2012, and there’s
something that’s come up now that we need to fix. We have a grid that displays
data to the users, and we have it nested within a RadPane on a page that is
divided up with a RadSplitter. Since we have so many different items that we
nest things within, I’ve been using percentages to say what percentage of the
page a control should take up. Our grid uses frozen header columns and we set the
width and height to 100% of the divs that it’s in.

The problem is that the scroll
arrows on the horizontal scroll bar don’t work. You have to drag the bar to get
it to move. I’ve narrowed the problem down to the properties that I can change to
get it to work. If I set the width and height to specific values, like 800px or
300px, the scroll arrows work just fine. However, when I try to set it to a percentage,
like 100%, then the arrow buttons don’t work anymore. I’ve pasted the code
snippet below.

If anyone could tell me what it is
I’m doing wrong and how I can get the width and height to fill the div and
still have the arrows work, I would greatly appreciate it! Thank you so much!

Hello, 

I have a radgrid on a modal popup. The first column is a checkbox and that HeaderTemplate is also a checkbox (select all). Everything behaves normally when single clicked. However, when a user accidentally double-clicks any of the checkboxes, the modal closes, which it should not - I actually prefer the postback not even fire. I was able to remedy the issue in Chrome and Firefox buy including the following:

<ClientSettings>
    <ClientEvents OnRowDblClick="RowDblClick" />
    <ClientEvents OnColumnDblClick ="RowDblClick" />
<ClientSettings>

As well as: 

function RowDblClick(sender, eventArgs) {
        return false;
    }

I am still having the problem with onclick posting back in IE. Has anyone else encountered this?

Hi,

I have some problems to filtering my grid with a FilterTemplate, the client-side event is fired but the method tableView.filter doesn't work properly. The filter return no records.

And my .js :

function OnRowDataBound(sender, args) {
    var dataItem = args.get_dataItem();

    if (dataItem.PPJ > 95) {
        args.get_item().get_cell("col_PPJ").style.background = "#D2FFD2";
    }
    else {
        args.get_item().get_cell("col_PPJ").style.background = "#FFD7FF";
    }

    if (dataItem.PPJ <= 0) {
        args.get_item().get_cell("col_PPJ").style.background = "LightGray";
    }

    args.get_item().get_cell("col_Date").innerHTML = moment(dataItem.Date).format("DD/MM/YYYY").toString();
}​

For information, my version of Telerik.Web.UI is 2014.3.1209.40 and the used date format is dd/mm/yyyy.

Do you have an idea about this problem ?

 Thank you,

Clément

Dear All,

 i followed the link http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/automatic-crud-operations/defaultcs.aspx and was able to see the data data in the RadGrid. But i was unable to edit or delete and when i tried to insert a row i wasn't able to see the text box where you can enter the data. i can only see a tick and a cross button . when i click on the tick button an empty row will be added to the table.

I am using RadGrid and showing 2 level hierarchial data master and detail.

I want to export just the detail table of a single master row to Excel

Is it possible to do it.

Note: I can export the complete Grid to Excel and it works.

Thanks,

I'm trying to find a DropDownList in my RadGrid using FindControl() method. But it's always returning null so it cannot find the DropDownList. I have the following HTML code:

And I'm trying to find "myDropDown" using this C# code:

But it cannot find the DropDownList. Can you tell me what I'm doing wrong?

Any help appreciated.

See Telerik column chart demo here:

http://demos.telerik.com/aspnet-ajax/htmlchart/examples/charttypes/columnchart/defaultcs.aspx 

Notice the labels above each column, such as "25000 sales". Now notice in the declarative code how this label is set:

<LabelsAppearance DataFormatString="{0} sales" Position="OutsideEnd"></LabelsAppearance>

I either need to set DataFormatString programmatically, or (better yet) I need to set it to the value of a column in my dataset from sql server. This column's data is not on the chart currently because I ONLY want that column's data used at the label at the top of each column. I can't figure out how to do either. How is it done?
