Questions on UI for ASP.NET AJAX Forum

We've been using Telerik Rad controls for a year now, and I always upgrade to the latest cut.

As of the recent Q2 2011 all upgrades we have done are conplaining they keep getting "A script on this page is causing Internet Explorer to run slowly" error, this is on a busy grid with only about 300 records, the problems go away if the records don't exceed about 30.

Have you seen this from other users?

We have clients on a mix of iis6 & 7 and IE 6,7 & 8.

We are having to stop the upgrade rollout until we get this resolved.

I have tried many things from disabling the viewstate to extending the MaxScriptStatements to 10,000,000.

Andy

PS - just seen the same error on my development system running ie9 and 290 records.
PPS - If I remove the RadAjaxManager I stop getting the error, so its an AJAX thing.

ImageHandler.ashx does not exist.

I have my global.asax file setup to report all errors to me via email. I keep getting the following error popup up 10 - 15 times a day on our BETA site (we are still on trial)

This is the exact error: The file '/QSSWeb2_Test/MySkins/Sigma/ImageHandler.ashx' does not exist.

We use custom skins. Any help would be appreciated.

Here's the full stack.

Get Value from ItemCommand event when using ItemTemplate at MasterTableView

I am working with a grid that I am using an ItemTemplate for the MasterTableView. In addition to the ItemTemplate I have three GridButtonColumns. When the user clicks one of these buttons, I want to get the Index of the record for that row (In my case the Unique Name is: AssetIdx).

Without the ItemTemplate the following code works fine:

GridDataItem item;

String ArticleID;

item = e.Item as GridDataItem;

ArticleID = item["AssetIdx"].Text;

With the ItemTemplate the code does not work.

I saw the following note in the demos (http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/cardview/defaultcs.aspx) :

"When you set item template all GridDataItems/GridEditableColumns (auto-generated or declarative) will be replaced with a single cell which will be used as a container for the templated content."

I have looked everywhere, and I can't find an example to get the value when the grid is treated as a single cell.

Can someone point me in the correct direction. Thanks!

Refresh Grid in parent page user control from Child windows

Hi,

I have a telerik grid which is inside a user control. On button click on that page, I am opening up a child window where I am adding some new records. After successful add, I want to refresh the grid with new records from child window. Could someone help me on this?

I found some demo here(see below link). But in the demo, the grid is in the aspx page, not in user control.

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=grid

Thanks

Date on x-axis with 1 month step

I am trying to plot a chart where datapoint ( x, y ) are as-
(datetime, number)

datetime is always in the format of "01-Month-Year" i.e. date part is always first of month
While adding X-axis range I am trying to use-

RadChart.PlotArea.XAxis.AddRange(dtBegin.ToOADate(), dtEnd.ToOADate(), 31);

RadChart.PlotArea.XAxis.LayoutMode = Telerik.Charting.Styles.ChartAxisLayoutMode.Inside;

RadChart.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;

RadChart.PlotArea.XAxis.Appearance.CustomFormat = "dd MMM yyyy";

RadChart.PlotArea.XAxis.AddRange(dtBegin.ToOADate(), dtEnd.ToOADate(), 31);

The problem with above code is that steps of 31 means that since not all month has 31 days we will end up with x-axis data point which will not be in 01-Month-Year format.

what I want on x-axis is like this

01-Nov-2010
01-Dec-2010
01-Jan-2011
01-Feb-2011
01-Mar-2011
01-Apr-2011

01-Jun-2011
01-Jul-2011
01-Aug-2011

01-Oct-2011
01-Nov-2011

01-Feb-2012
01-Mar-2012
01-Apr-2012
01-May-2012
01-Jun-2012
01-Jul-2012
01-Aug-2012
01-Sep-2012
01-Oct-2012

what I get is something as shown in attached image.

How can I add date alone x-axis with steps of 1 month.

RadGrid not displayed intially on dynamically loaded user control

I have a RadGrid in a dynamically loaded user control. When the page that hosts the user control is initially loaded the RadGrid does not appear. I have to click some buttons that are configured via a RadAjaxManagerProxy on the user control to update the RadGrid before it appears. Once the RadGrid has appeared all operations behave normally. Any ideas on how to display it on the initial page load??

Vertical Header Text Affecting Borders

I have a RadGrid (v2009.2.701.35) using the Web20 theme. In my attached screen shot, the grid in the upper half is the grid with the default horizontal text in the header. Notice the uniform borders between all of the header columns. The grid in the lower half is a result of changing the header text to render vertically. Now notice the difference in column widths between columns 1 & 2 vs columns 2 & 3 or 3 & 4. Is there any way to get uniform header column borders with vertical header text? Here's my CSS tweak w/ changes in bold:

.RadGrid_Web20 .rgHeader, .RadGrid_Web20 .rgHeader a

{

color: #ffffff !important;

font-family: Arial !important;

font-size: 8pt !important;

font-weight: bold !important;

text-decoration: none;

text-align: left;

border-color: #FFFFFF !important;

writing-mode: tb-rl !important;

filter: flipV flipH !important;

}
