RadToolTip in usercontrol of grid - this._popupelement is null

Hi,
     I have a grid. Within the grid, I am using a usercontrol for an edit/insert form. In this form, there is a drop down that comes from yet another usercontrol. Inside this second usercontrol I have a radtooltip that I am using for the user to input a name.
   The problem is that when the radtooltip is called I get this javascript error message ...
   this._popupelement is null or not an object.
The interesting thing is that this happens in IE7, but in FF, the radtooltip displays for a second or two, then disappears and the grid
suddenly gets scroll bars.
  Any advice on what I might need to look at ?
thanks for your time.

[Solved] I'm seeing a shedload of calls to RadUploadProgressHandler.ashx

I have a page that appears in a RadWindow.

The page contains a RadMultiPage control and one of the PageViews includes a RadAsyncUpload control.

Each time the page does an Ajax callback I'm seeing several calls to RadUploadProgressHandler.ashx.

Questions:

Is that normal?
Can I limit the number or requests?

In almost every case when I've been testing, I've not even had to both uploading anything or even visit the PageView that has the Upload control on it.

[Solved] Grid row reordering with self-referencing hierarchy

I have a RadGrid that I'm using self-referencing hierarchy and row reordering. I would like an example of how to trap whether a parent row is being dropped as a child of itself.

For tree view, I use something like:

if(sourceNode.Equals(destNode) || sourceNode.IsAncestorOf(destinationNode))

	return;

RadComboBox externalcallback page is removed with Telerik Up gradation now what should be the RadComboBox.ID

Hi,

I am facing the following problem on RadComboBox. Scenario is as below:

1. We generate radcombobox within grid, other custom container models and independently.
2. In our earlier fix we used to have RadComboBox along with external call back page which is the streamer page and following is the definition:
RadComboBox m_combo = new RadComboBox();
m_combo.ID = string.Empty;
m_combo.SkinID = TEXT_SKIN_ID;
m_combo.EnableViewState = false;
m_combo.ExternalCallBackPage = "~/ComboBoxStreamerPage.aspx";

and in streamer page oninit event we have following code

RadComboBox comboBox = new RadComboBox();
   comboBox.ID = Request.QueryString["rcbServerID"];
   comboBox.EnableLoadOnDemand = true;
   comboBox.ShowMoreResultsBox = true;
   comboBox.EnableVirtualScrolling = true;
   comboBox.EnableItemCaching = true;

This was working fine unless we upgraded telerik and no longer using external call back page instead using a web service.

My problem is I can't give a static id to combo since it will give me same IDs exception if added on same page multiple times. I also can't give new GuidID because it is giving me some other problems.

Please suggest me what should be the RadComboBox ID instead of string.Empty because now there is no external call back page.

Thanks,
Ifthekhar

Random extra space in table in repeater

I have a table within a repeater. Sometimes within my table, the cells have extra space between them. It is very random. I have set table width, colgroup for the table, and colspan for each td. Most everything comes out correctly except for a few random cells that get pushed to the right showing blank space in the table. I am using the same code for different data, and sometimes it comes out fine, sometimes it adds the space. I have attached "tableinrepeater.png" that shows an example of this. The other files show a bit of code and style.

Call client event onRowDataBound using JQuery

Hi Gurus,

I have a requirement that ensures i bind the grid @ the client side. So I did that using webservice. I have a bunch of images & hyperlinks in the grid. So when I use the onRowDataBound event & display all the images & the hyperlinks (the hyperlink & image tag are put in the itemtemplate), it initially displays the grid in the attached manner. It then takes a 3-4 secs to load the images. Building the image url & the hyperlink url is done in the onRowDataBound in JS. I know this is obviously slow.

So i wanted to call the onRowDataBound using the JQuery in the document.ready & populate build all the URLs using JQuery which I think could be faster than the regular JS. I started doing this in the following way:

<script language="javascript" type="text/javascript">

$telerik.$(document).ready(function() {

alert("Document is ready");

$('.rgMU').onRowDataBound(function rgMU_RowDataBound1());

});

function rgMU_RowDataBound1(e) {

debugger;

var row = e.row;

var dataItem = e.dataItem;

alert("IN the event");

}

</script>

BUt for some reason, the event never fires up. So once the event fired up, how do I populate the URLs (the URL for each row is coming from the DB). So it should be part of "args.get_item().findElement("Img1URL");" but how do I bind this with the JQuery.

Can someone gimme an example?

Thanks
Bobbie

How to ajaxify a GridButtonColumn ?

Hi I need to ajaxify a column in a grid in a Usercontrol... i did a search and found an example on how to achieve it but the sample was using an asp button...
How can i achieve the same thing without the use of the asp:button

<telerik:GridButtonColumn ButtonType="PushButton" CommandName="ViewResults"

FilterControlAltText="Filter ViewButton

column"<BR>

Text="View Results" UniqueName="ViewButton" DataTextField="CRM_TRACKING_ID"

HeaderText="CRM Tracking ID"><BR></telerik:GridButtonColumn>

Also, just to confirm, Can i still use this snippet even if mine is called from a user control with a RadAjaxManagerProxy? The AjaxManager is from my Master Template...

protected void RadGrid1_ItemCreated(object sender, Telerik.WebControls.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

ImageButton ImageButton1 = (ImageButton)item["TemplateColumn"].FindControl("ImageButton1");

RadAjaxManager1.AjaxSettings.AddAjaxSetting(ImageButton1, TextBox1, null);

}
