Hi
We have an aspx page with a usercontrol lying directly in the page and a tabstip with usercontrols dynamically loaded on each tab on demand.

Based on the save operation of user control inside a particular tab, we would like to refresh data in the user controls that direcly place in the aspx page.

But the problem is the evenhandler is always null inside the usercontrol in the tabstrip.

Are we using the right code to handle this?

Here is the code from ascx control residing inside a tab:

private System.EventHandler ButtonResSaveClicked;

public event EventHandler BtnResSaveClicked

{

add

{ ButtonResSaveClicked += value; }

remove

{ ButtonResSaveClicked -= value; }

}

protected void btnSave_Click(object sender, EventArgs e)

{

//Perform save operation

if (ButtonResSaveClicked != null)

{

ButtonResSaveClicked(sender, e);

}

Related code in aspx page:

ucFromTab.ButtonResSaveClicked+= ucInPage.RefreshData;

Any of your response will be of great help to me.

ContextMenu with nested grid

Hi,

Is it possible to attach a context menu to a nested grid ? I currently have a radGrid with a nestedGrid and I use the following code to attach a menuContext

function RowContextMenu(sender, eventArgs) {

var menu;

var ownerTable = eventArgs.get_tableView();

if (ownerTable.get_name() == "Grid") {

menu = $find("<%=RadContextMenuUser.ClientID %>");

}

else if (ownerTable.get_name() == "NestedGrid") {

menu = $find("<%=RadContextMenuUsersRole.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

document.getElementById("radGridClickedRowIndex").value = index;

document.getElementById("radGridClickedTableId").value = ownerTable._data.UniqueID;

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

For the "parent" grid, it works really great, but it doesn't work for the nestedGrid. In fact, I have the following error :
Cannot call method 'get_element' of undefined.

So, anyone may help me please ?

Editing a hyperlink causes hyperlink above to disappear when contains br

Example:

<a href="/test.pdf" target="_self">test1<br />
</a>
<a href="/test2.pdf" target="_self">test2<br />
</a>

Clicking on the hyperlink manager for "test2" and changing an attribute on it like tooltip or link then when clicking ok in the dial of the hyperlink is removed from test 1?

This only happens when the link has a BR in it.

Unfort. its not as easy as to say to users not to put BRs in as all you have to do is type two lines of text and highlight one and convert to a hyperlink and it encapulates the BR ( In design view ) so its very easy for the end user to produce this html not knowingly.

I have just tried this on the telerik demo site and it does the same?

-Appreciate some Help please?

Many thanks,
Jason

RadTabStrip, RadMultiPage, and RadGrid controls become unresponsive when too many rows in the RadGrid control !?!

Hi,

I've been developing and/or supervising development of .NET Web applications using r.a.d. Controls for ASP.NET AJAX for quite some time now and this is the first time ever I post a thread in this forum.

I'm the technical owner of a VB.NET 3.5 Web application developed some two years ago using release 2008.03.1314 of r.a.d. Controls for ASP.NET AJAX. I guess shortcuts followed then (the code is not so good...) are finally catching up, as they usually do, and users of the application are now encountering a quite peculiar problem.

In short, there is this RadGrid control within a user defined control embedded within a RadMultiPage control and whose visibility is toggled through a RadTabStrip control; rows within the RadGrid are managed through an ItemTemplate element and, especially, an image is available for each row in the grid, the image being retrieved from a database and generated dynamically through a typical call to a .NET page that returns a binary output stream (GridImageColumn column type was not available back then): something like ImageUrl='<%# "ViewImage.aspx?ImageID=" & Eval("ImageID").ToString()%>'... Well, it appears that everything works fine for as long as there is at most 7 rows per grid pages (users can set page size at will), not one more: more than that RadTabStrip, RadMultiPage, and RadGrid controls become unresponsive and any user action results in a complete page refresh, nothing more. On the other hand, if I change the code and force the same image to be reused over and over again, say, ImageUrl='<%# "ViewImage.aspx?ImageID=3"%>'things work as expected no matter what the grid page size is. I know this sounds strange but after hours of narrowing the problem down, it all comes down to this!

I could send the complete code but it is quite large and, quite frankly, I'm not sure how it would help. However, f it can be of any help, the RadGrid control is configured as follows:

<telerik:RadGrid ID="rgDirigeant" runat="server"

To tell the truth, I'm not sure the problem is even directly due to r.a.d. controls but since they are all over the place, I figured it wouldn't hurt posting this thread in this forum. Note that I'm not considering this problem as a Telerik bug at this point: I'm actually more interested in pointers and insights. Has anyone encountered similar problems? Does my description ring any bells? Am I missing something here? And please, do not recommend the obvious such as refactoring the code or upgrading the r.a.d. Controls for ASP.NET AJAX library: I'm on tight budget and time constraints here. Again, I want to know what's going on!

If anybody wants more information, I will be happy to collaborate.

Thanks in advance.

RadWindow Cross Browser Size Problem..

Hi ,
       I had a RadWindowManager and Radwindow in a Masterpage.I used to open Radwindow where ever
       i needed using below script.

    function OpenRadWindow() {
            var parentWindow = radopen("MyPage.aspx", "rwTest");
            parentWindow.setSize(400, 160);
            parentWindow.SetTitle("Test RadWindow");
            return false;
        }

and this is my design.

<telerik:RadWindowManager ID="RadWindowManager1" Style="z-index: 10000" runat="server"
            VisibleStatusbar="false" Modal="true" Behaviors="Close,Move"
            ShowContentDuringLoad="false">
            <Windows>
                <telerik:RadWindow ID="rwTest" runat="server" VisibleTitlebar="true" VisibleStatusbar="false">
                </telerik:RadWindow>
            </Windows>
</telerik:RadWindowManager>

I have used the setSize(400, 160) to set the size.My problem is RadWindow is opened in different sizes
in different browsers.Only in IE8 i can set the width and height correctly.In other browsers size differs.
I have also tried set_width and set_height,but of no use.Can anyone help me how to set size of Radwindow
same among all browsers.

Also can any one tell me how to set image for RadWindow from clientside,because im using same Radwindow
for my all needs and i cannot set ImageUrl for RadWindow itself.I have referred the below url

http://www.telerik.com/help/aspnet-ajax/window-programming-radwindow-methods.html

and in that i cannot find a way to setimageurl by using something like parentWindow.SetImageUrl("Image.png");
Please help me....

Regards and Thanks,
Titti Skaria.

Disable update but keep insert in GridBoundColumn?

Hi. I have a GridBoundColumn in a RadGrid, and I'd like to know how I can disable updating the value in the column, while keeping the ability to insert it, as the readonly attribute seems to affect both updating and insertion.
Thanks in advance.

Grid don't keep is data

Hi

I have a really big problem. I have two grids on two differents windows. One grid must have a list of user and the other must be empty at his first load. Then, I select data in the first grid and I transfert it into the second grid. To do that, I'm using a dataSet in a singleton class. So, the first grid add the selected item in the dataSet and the seconds grid show what his in the dataSet. So far, so good. When I close the window that have the second grid (let's call it winGridB), the dataSet is clear and so, when the winGridB is open again, the grid is empty, like I wish. The problem come when I close the browser. Because I used the event onClientClose and this event doesn't seem to be call when I close the browser, the dataSet isn't clear. So, I when open the winGridB again, there are old data in it. To correct this problem, I try to clear the dataSet in the event Page_Load, OnLoad and OnInit, but it seem like those event are called each time the page is refresh. So, if I add data on the dataSet, the grid in the winGridB will be rebind to get the latest data and the page will be reload, which mean the dataSet will be clear. So, I'm stuck !!!

To resume, I'm using a dataSet with my grid and I don't know how to clear my dataSet when the browser is close. If anybody have a idea, just let me know.
Thank you

David
