hello,

i want to set default size in Dropdownlist Size using tool file:

iam using this code:
<script type='text/javascript'>
function OnClientLoad(editor, args) {

var fontFamily = editor.getToolByName("FontName");
var fontSize = editor.getToolByName("FontSize");
var timeout = (document.all) ? timeout = 0 : timeout = 1000;
setTimeout(function () {
fontFamily._element.getElementsByTagName("span")[0].innerHTML = "Arial";
fontSize._element.getElementsByTagName("span")[0].innerHTML = "2";

Hiding rows in Biff excel export

I have a grid where I hide rows on the client side based on a combobox selection. Something like this:

var grid = $find('<%=MyGrid.ClientID %>');

var masterTableView = grid.get_masterTableView();

// iterate through the rows and then use the

masterTableView.showItem();

//and

masterTableView.hideItem()

//methods

When I do a biff export, all the data is exported, regardless of the visibility I just set on the rows client-side.

My goal is to keep the same rows hidden for the export.

My idea was to use the grid's BiffExporting event to manipulate the ExportInfrastructure.Table object, and hide the same rows. Is this possible? Or am I going about this the wrong way? I'm not even sure the visibility of the rows is available to me server side since I set them on the client side...

ajaxify specific controls dynamically ArgumentNullException no page parameter

Hi All,

I am attempting to ajaxify specific controls dynamically. I have a repeater and i want to ajaxify image buttons inside the repeater.

On ItemCreated for the repeater i am:

protected void RptCategories_ItemCreated(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                ImageButton imgbtn = (ImageButton)e.Item.FindControl("iBtnRemoveCategory");
                this.RadAjaxManager1.AjaxSettings.AddAjaxSetting(imgbtn, RptCategories, RadAjaxLoadingPanel1);
            }
        }

The line where i am adding the AjaxSetting i am getting the error: ArgumentNullException was unhandled by user code, value cannot be null, Parameter Page.

It seems the RadAjaxManager doesn't know where it is.. this is a form page with a masterpage.. no usercontrols..Please help. THanks.

GridControlTelerik

Grid = UICommon.CreateMainetGridTelerik(this, SInfo.Name, RecordId, CanUpdate && !isReadOnly, controlStyles);

ViewState Problems

I've got a general ViewState question. Here's how I'm using Telerik and Ajax in my Web App.

1. Using an .aspx page as the shell that loads a web user control (.ascx) that acts as sort of a master page to additional (.ascx) pages based on what the user selects. So Master.ascx has a tree control and this tree envokes different .ascx pages to load on the right side of the page based on what users select.

2. I've got a class that is keeping a session variable to remember data based on user clicks

So, all is well until I open a second window and cut and paste the same exact URL into it.
I'm not forced to login it just opens just like the original window.

Here's where it gets hairy. If I start to click in Window 2, I am able to load all of the secondary .ascx pages as I go without any issues. Now if I go back to Window 1 I get all sorts of errors referring to ViewState not being able to load.....

This error seems very generic and I'm unable to get to the bottom of it. Any ideas where I should start looking?

Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Trigger spellcheck on RadEditor in a hidden tab

Hi,

We have a requirement to spellcheck on form submission. Since the form is quite big, we had to use RadTabStrip to show the form in the multi tabs using RadMultiPage. I got the solution from here that triggers the spellcheck on form submission. However, this does not work if the RadEditor is in an inactive tab. Is there a way to achieve the spellcheck on hidden RadEditor on submission?

Thank you,

James
