creating RadGrdid from codebehind

Hi,

                I created grid dynamically and paced button on page.It is working fine except column width when i browse the page first time.
                I am also displaying seach conditions in RadWindow when user clicks on button.

Note : I created xml file for columns definations and using to generate the bound columns.

Below is my code for HTML,codebehind, xml and xml helper functions.

Can you please help me to resolve the below issues?

Issues List :
               1. I am getting extra columns when i click on pager to selct particular page or column for sort.
               2. I want to sort the records within the page not on data source, Is there any way we can sort the records present in the page?
              3. How can we set the column width in RadGrid?
              4. I am getting the popup with retry and cancel buttons with the below message when i seach the records other than first page or before selecting the column sort or paging. Can you please advice me on this?

To Display the webpage again, Internet Explorer needs to resend the information you've previously submited

If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click Retry to display the webpage again.

Duplicating markup on save

We have an issue where duplicate markup is being created when users are editing wiki content using the Rad Editor.

An example is when a user clicks edit on a wiki page, makes NO changes and clicks ok, duplicate <p> tags are inserted into the page causing formatting issues.

We have also seen this issue with <li> tags.

This is affecting v5.2.0.0 of the MOSS rad editor.

RadGrid with MS DropDownList

I have MS DropDownlist as the ItemTemplate column in the RADGrid with other columns. I am binding DropDownList in ItemBound method(similar to http://www.telerik.com/help/aspnet/grid/grdoperationswithdropdownlistinedititemtemplate.html). The button on page fires postback event and reload grid. I have saving the selected value of DropDownlist in Datatable and rebind the grid.

The DropDownList shows values but loses the selected value.

My code is very similar to link above with extra Button rebind the grid. There is not EditTemplate.

web.config Forms Authentication

I'm not sure if I missed it in the docs, but this should probably put somewhere a little bit more explicitly. Heck, maybe the code that adds it can check for any Forms authentication and raise a warning... or always add it.

When ever using Forms based authentication the Telerik.Web.UI.WebResource.axd is denied access and all scripts fail.

    
            <authentication mode="Forms"> 
        
                <forms name=".XAPP" path="/" loginUrl="~/Login.aspx" protection="All" /> 
        
            </authentication> 
        
            <authorization> 
        
                <deny users="?"/> 
        
            </authorization>

Needs to this appended after the system.web element:

    
            </system.web> 
        
            <location path="Telerik.Web.UI.WebResource.axd"> 
        
                <system.web> 
        
                    <authorization> 
        
                        <allow users="*"/> 
        
                    </authorization> 
        
                </system.web> 
        
            </location>

OnRowClick and AllowRowSelect

Is it not possible to have both AllowRowSelect and OnRowClick in the ClientSettings?

I can get either one to work properly when the other is not present. With the setup below the OnRowClick functions, but my clicked row is not highlighted anymore.

<ClientSettings EnablePostBackOnRowClick="true">
<Selecting AllowRowSelect="True" />
<ClientEvents OnRowClick="OnRowClick" />
</ClientSettings>

<script language="javascript" type="text/javascript">
function OnRowClick(index)
{
    var ContactId = this.GetCellByColumnUniqueName(this.Rows[index], "ContactId").innerHTML;
    var AccountId = this.GetCellByColumnUniqueName(this.Rows[index], "AccountId").innerHTML;
    var FullName = this.GetCellByColumnUniqueName(this.Rows[index], "FullName").innerHTML;

    document.getElementById('<%= hdnContactId.ClientID %>').value = ContactId;
    document.getElementById('<%= hdnAccountId.ClientID %>').value = AccountId;
    document.getElementById('<%= hdnContactName.ClientID %>').value = FullName;

    return false;
}

ToolTip manager/Grid/Grouping

I have a grid and every row has a hyperlink that gets added to a tooltip manager's target control collection (an example of an id is:ctl00_ContentPlaceHolder1_rgBkrInvoice_ctl00_ctl06_hlDiscussion). When I do a single grouping, the tooltips don't come up, and the target controls have odd numbers instead of even (ctl07 instead of clt06, etc). When i group a second time everything works again and the target controls are back to even numbers. Any ideas how to get this working?

Thanks
