"Firewall" Issue when a Large Number of RadListBox Items are Selected

I am unable to successfully submit an ASP.NET web form when a large number of RadListBox items are selected (79 in this case). However, if I select a significantly smaller number of items, I am able to successfully submit the form. After consulting with a firewall SME, I was able to verify that the following parameter was causing the "network security engine" to reject the request: "radListBox_ID_ClientState={"logEntries":[{"Type":1,"Index":"1","Data":{"value":"6","selected":false,"text":"TextValue_1"}},{"Type":1,"Index":"2","Data":{"value":"15","text":"TextValue_2"}},...,{"Type":1,"Index":"79","Data":{"value":"101","text":"TextValue_79"}},"}}],"selectedIndices":[0],"checkedIndices":[],"scrollPosition":1629}.

Obviously, the payload for this parameter is significantly large. Consequently, the network "network security engine" exceeded its set number of maximum recursions to verity the content of this parameter was not malicious. Therefore, the request was rejected when a user selected a large number of items via RadListBox control, causing a page error. Is there a known work around for this issue? Is there a way to reduce the payload when submitting a form with a large number of RadListBox items are selected (e.g., > 100)? Thanks in advance!

RadChart Alternating Background StripLines On ASP Ajax control

I want to show an alternating background colour for the X axis on a line chart on the ASP.Net Ajax RadChart control.
I have found this article that shows the StripLine property for Silverlight and WPF chart control but I cannot find this property on the Ajax control. Maybe I'm just not finding it - how can I set the background colour to stripe vertically in line with the X axis columns.

Thanks.

Radcombobox client validation being triggered on scroll

I have a radcombox with custom validator for checking if any item is selected in the list; I have virtual scrolling enabled. When I search for items containing some text, the items are populating in the combobox and if there are many items, the scroll bar is showing. When I select the scroll down arrow , the validation is getting triggered. Ideally it should not as I am just scrolling. The validation should only trigger when I do not select an item in the radcombobox and I lose control focus. Is this a bug in telerik?

<telerik:RadComboBox ID="ListSelect" runat="server" Width="192px" EnableLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true" WebServiceSettings-Path="../../ws/AutoSuggest/AutoSuggest.asmx" AllowCustomText="true" Filter="Contains" OnClientItemsRequesting="SearchAutoSuggest" WebServiceSettings-Method="GetResults" OnClientSelectedIndexChanged="SelectAutoSuggestValue" AutoPostBack="false" MaxHeight="400px" OnClientDropDownOpening="selectText" MarkFirstMatch="true" OnClientItemsRequested="highlightText" OnClientDropDownOpened="highlightText" >
</telerik:RadComboBox>

<asp:CustomValidator ID="Validator_PatientGroupSelect" runat="server" ControlToValidate="ListSelect" ClientValidationFunction="checkValidSelection" />

Get HTML output of telerik controls in code

Hi there,
For a ASP.NET project we are working on, we need to have the capability of generate Telerik control HTML in server side code and then return the controls's html to front-end via client script for dynamic replacement.
We have been unsuccessful in getting Telerik control HTML output via server side code and wondering if everyone have had similar experience can share some knowledge and solutions.

Please refer to the code below on how we are trying to get Telerik control HTML output:





StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
Telerik.Web.UI.RadComboBox rcb = new Telerik.Web.UI.RadComboBox();
rcb.ID = "sokmething";
rcb.RenderControl(hw);   // Freeze here during execution 
string b = tw.ToString();

Grid 100% width colums width problem

Hi!

I have a RadGrid control on page with 100% width.
When vertical scroll appears on the grid, its extends page width with scrollbar's width. In this case the column's header and item style width is the same.
I use tablelayout:fixed property in mastertableview. If I don't use this property the problem is still exists.

If I put the radgrid in a table with table-layout:fixed, its doesn't extend page, but the column's header and item style width not the same.

How should I resolve this issue?
Thanks

Passing datatable to a web user control w/ radgrid

I am trying to create a page that will display a dynamic set of results based on user input. The gist is that the results will look something would contain specific info about a customer site, followed by a grid with the detailed results for that particular location. Something like:

Site: sitename, city, state
grid w/ satisfaction survey results

The user would be able to pick either a single site, all of the sites that reports to them, or to a subset. Since this is a dynamic list, I thought it would be best to use a user control with the grid. I already have a datatable that has the results for all of the selected sites, so I want to pass the datatable to the user control, then let the control apply a filter.

So I created a user control, and the code-behind for it looks like:

namespace SurveyResults

{

public partial class resultsGrid : System.Web.UI.UserControl

{

private DataTable _dtResults = null;

public DataTable dtResults

{

get

{

return _dtResults;

}

set

{

_dtResults = dtResults;

}

protected void Page_Load(object sender, EventArgs e)

{

gridResults.DataSource = _dtResults;

gridResults.Rebind();

}

Then I added a placeholder to my primary page, and added the following code:

// dtResults is a datatable that contains the results for all sites.  I have verified that it does contain data at this point

_resultsGrid = (resultsGrid)Page.LoadControl("resultsGrid.ascx");

_resultsGrid.dtResults = dtResults;

phResults.Controls.Add(_resultsGrid);

When I set a breakpoint on the set property for dtResults, I am only getting a null value. So then when the page_load for the user control runs, the datasource is null. I don't get an error, I just don't get a grid either.

I will be very much appreciative if someone can point out what it is that I am doing wrong here.

Thank you!
