here is the javascript:



<script type=

var cbxCSI = new Array(4);

var rcbCSI = new Array(4);

function OnLoad() {

var onLoadCSIs = ['<%=objBidder.BidderCSI1%>', '<%=objBidder.BidderCSI2%>', '<%=objBidder.BidderCSI3%>', '<%=objBidder.BidderCSI4%>'];

[RadTabStrip] Tooltip does not work

Hello,

I use the component RadTabStrip. It is impossible to change the tooltip of a RadTab. It automatically changes the Text property. The value of the property Tooltip does not work.

Internet Explorer cannot display the web page

Hi,

I'm experiencing problems with the RadUpload sometimes working great with progress indicator for files up to 2GB and sometimes I get "Internet Explorer cannot display the web page." The files can be as smaller than 1MB and I can still have the same problem. I did not seem to have this problem when the server was on our internal network, where of course the network speeds are much faster. Tthe "Internet Explorer cannot display the web page" can come up after 10 seconds, 20 seconds, 30 seconds, 40 seconds, ...after executing the Submit button to perform the upload. I've played with client browser timeout settings, set IIS 7.5 uploadReadAheadSize to 5MB, set IIS 7.5 connection timeout to 3 hours (10800 seconds), but I can't seem to solve this problem. The RadUpload utility logs in the IIS web logs that it is uploading, and the last log when I get "Internet Explorer cannot display the web page" is that it is uploading. There are no other logs anywhere. Even if the network is dropping packets or something, is there a way to build in some better error control handling so that when this happens the upload session can stay in progress?

Prevent a bad image from blowing up the code

Hey,

I was following the example for using a binary image with a listview to display images etc. allowing users to upload, and edit them.

The code is great except in the event the user uploads a bad image, during postback when the listview is displayed it blows up and throws errors saying the binary data is corrupted.

I know there should be a way to grab hold of the data during the ItemDataBound event, and catch the error, and ignore it or substitute the image with something stored on the website like a badimage.jpg

can someone help with this thanks

Hiding a RadGrid, then showing is losing it's Skin

Hi all,

If I have a RadGrid hidden on the page (either through setting it's property or doing it dynamically at runtime in Page_Load), and then later make it visible, it looses all it's Skin information. Here's a quick sample page I created to demonstrate the problem.. I tried also using the RadScriptManager and got the same effect.

Thanks!!

Error : Selection out of range Parameter name : Value

Hi,

I have a problem since few days with the RadCombox on LoadOnDemande.
The load is OK, but when i select an item in the list and i post the page, i have an error message : "Selection out of range Parameter name : Value"

I don't understand the problem, the same code worked before.

Thanks for help

Aspx code :

<telerik:RadComboBox ID="MRLieu" runat="server"

AllowCustomText="true"

ItemRequestTimeout="1000"

Filter="Contains"

ShowDropDownOnTextboxClick="false"

MinFilterLength="2"

EnableLoadOnDemand="true"

EnableVirtualScrolling="true"

ShowToggleImage="false"

OnClientFocus="ChangeOu"

OnClientItemsRequesting="OnClientItemsRequesting">

<webservicesettings method="GetLieu" path="~/Utils/WebService/Utils.asmx" />

</telerik:RadComboBox>

JS Code :

function OnClientItemsRequesting(sender, eventArgs) {

var context = eventArgs.get_context();

context["coffret"] = "16";

}

function ChangeOu(sender) {

var lieu = $find("MRech_MRLieu");

lieu.clearSelection();

lieu.clearItems();

}

C# Code WS :

[WebMethod]

[ScriptMethod]

public RadComboBoxItemData[] GetLieu(object context)

{

IDictionary<string, object> contextDictionary = (IDictionary<string, object>)context;

string txt = contextDictionary["Text"].ToString();

int coffret = Convert.ToInt32(contextDictionary["coffret"]);

txt = txt.Replace("'", " ");

txt = txt.Replace("\"", " ");

txt = string.Concat("\"", txt, "*\"");

string sql = @"MyRequest";

ConnexionUtil cnnUtil = new ConnexionUtil();

DataTable data = cnnUtil.ExecuteRequeteDataTable(sql);

int itemOffset = Convert.ToInt32(contextDictionary["NumberOfItems"]);

int endOffset = Math.Min(itemOffset + NBITEMS, data.Rows.Count);

List<RadComboBoxItemData> result = new List<RadComboBoxItemData>();

RadComboBoxItemData itemData;

for (int i = itemOffset; i < endOffset; i++)

{

itemData = new RadComboBoxItemData();

itemData.Text = data.Rows[i]["nom"].ToString();

itemData.Value = data.Rows[i]["id"].ToString();

result.Add(itemData);

}

data.Dispose();

C#
if (RadUpload1.UploadedFiles.Count > 0)
{
    foreach (UploadedFile validFile in RadUpload1.UploadedFiles)
{
    string targetFolder = Server.MapPath("/attachments/");
    validFile.SaveAs(Path.Combine(targetFolder, validFile.GetName()), true);
}
labelNoResults.Visible = false;
repeaterValidResults.Visible = true;
repeaterValidResults.DataSource = RadUpload1.UploadedFiles;
repeaterValidResults.DataBind();
}
else
{

Telerik chart, control items overlap whit popup in Internet Explorer 6

I have a page that contains one Button and one Iframe.
The Button opens one popup(jquery dialog) and the Iframe contains one Telerik.ReportViewer.WebForms.
My problem is that when i open the popup that is above the report, the dropdown from the report tools overlaps the popup.

This problem occurs only on internet explorer 6.

P.S. I have noticed that the export feature does not work :(
