Hi,

I have a main page with a radgrid. Double clicking the grid opens up a radwindow that lets the users edit the grid row data. I want the grid on the parent page to refresh without having to do a full page refresh. I tried the Ajax call. Everything seem to work as expected. But the grid does not seem to refresh. I can debug the code and see that the server side code does fireup and the grid rebinds successfully. It just does not show up on screen. Here is my code.

On the main page, I have the AJAX manager as below.

telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="grdAdminList" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

Here is the server side code:

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
if (e.Argument == "Rebind")
{
grdAdminList.Rebind();
}

Here is the code that I have on my radwindow close:
This function calls the actual refreshGrid function that is on the main page.

function

refreshGrid()
{
GetRadWindow().BrowserWindow.refreshGrid();
}

Main page function:
function refreshGrid()
{
$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
}

What am I missing here?

Thanks!

Hi Shinu,

Thank you for the quick response. But I am not sure how the links you provided are related to what I am trying to accomplish. I do not have an ajaxpanel in my app. I only have ajaxmanager. The code behind is working as expected and the ajax request is being processed as well. When I debug the code, I can see it stepping through the ajax request and rebinding the grind which then has the updated data. It's the grid on the screen that does not show the updated data. To me it looks like the client side is missing something. Please look at my code that I posted earlier and confirm that at least I am going in the right direction.

Thanks!

Ok, while there was no response for my previous question, here is another one.

I am now trying to move the AjaxManager control to the master page and manage ajax calls on the content page using the AjaxManagerProxy control.

After doing so, when I try to initiate the ajaxrequest call using javascript, it does not seem to find the ajaxmanager at all. Here is the code to make the ajaxrequest call.

var

radMgr = $find("<%= RadAjaxManagerMaster.ClientID %>"); (did not work)

radMgr.ajaxRequest(

"Rebind");

Also tried,

var radMgr = $find("<%= RadAjaxManagerProxy.ClientID %>"); (did not work)

radMgr.ajaxRequest(

"Rebind");

And finally tried,

var radMgr = $find("<%= RadAjaxManagerMaster.GetCurrent(Page).ClientID %>"); (did not work)

radMgr.ajaxRequest(

"Rebind");

All of the above did not work. In the first and the last case, it kept saying that the control did not exist in the context. The second option did not give me any error message, but did not work either.

Please let me know how I can get it to work.

Thank you!

Hi Vithiya,

I think that the following online demo:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Controls/Examples/Integration/GridAndWindow/DefaultCS.aspx?product=grid

and the demo project from the relevant KB article on our site:

http://www.telerik.com/support/kb/article/b454K-gmb-b454T-cba-b454c-cba.aspx

can become the basis for your implementation. Additionally, how to reference the ajax manager in master/content page scenario and trigger ajax requests from the client you can learn from the resources pointed below:

Ok, after going through the articles that you pointed, I am still stuck at one point. I have made all suggested changes like moving hte ajax manager to the master page, creating an ajaxmanagerproxy in the content page and have added settings to the proxy. Now, when I tried to initiate the ajax request on the server side, it does not work.

When I use the below code, I get a null exception (System.NullReferenceException: Object reference not set to an instance of an object.). I am trying to ajaxify a radgrid in the content page using the proxy.

var

radMgr = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

radMgr.ajaxRequest;

Please advice!

Thank you!

I am having a similar problem using the proxmanager to rebind a datagrid I get the following error

The best overloaded method match for 'Telerik.Web.UI.RadAjaxManager.GetCurrent(System.Web.UI.Page)' has some invalid arguments

I have a standard web page with the radscript manager and radajax manager.

I have a user control based on the rad grid editing demo. instead of the ajax manager I am using the manager proxy in my user control

this is the sample code i used to base my user control

Thank you.

It does not seems to be your case but just in case someone has the same problem the I did...

I did not know that I needed to authorize the events coming from the RadAjaxManager1to also update the grid. That did the trick for me and it seems logical.

EnableViewState="false" should not be an option here to solve the problem...

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

I've used all the code provided, but I still cannot get my radgrid to refresh. My datasource is bound in my code behind. I did a watch on the binding, and the data is there like it's supposed to be, the grid is just not refreshing on the screen/page.

I don't want to set enableviewstate="false" unless I have to. Is there another way around this? I am providing my code below.

ASPX:

<script type="text/javascript">

function onRequestStart(sender, args) {

if (args.get_eventTarget().indexOf("excelExport") >= 0) {

args.set_enableAjax(false);

}

function ShowInsertForm() {

var combo = $find("<%= RadComboBox1.ClientID %>");

var comboItem = combo.get_selectedItem();

if (!comboItem)

{

window.radopen("AddComment.aspx", "UserListDialog");

}

else {

window.radopen("AddComment.aspx?PO=" + comboItem.get_value("PO"), "UserListDialog");

}

return false;

}

function refreshGrid() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

Your code looks fine to me... Just, could you clarify when you expect your grid to refresh?
I guess that you expect the grid to refresh after you add a comment with your popup form and close it?
Because I don't see what is calling the javascript refreshGrid method.

this is probably obvious for you, but just in case, you have to close your popup like that:

protected void btnClose_Click(object sender, EventArgs e)

{

//ScriptManager Enables AJAX In Your Web Apps

//http://msdn.microsoft.com/en-us/magazine/cc163354.aspx

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "mykey", "CloseAndRebind();", true);

}

which will call the folowing popup javascript:

<script type="text/javascript">

//reload the parent

function CloseAndRebind(args) {

GetRadWindow().Close();

GetRadWindow().BrowserWindow.refreshGrid(args);

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow; //Will work in Moz in all cases, including classic dialog

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow; //IE (and Moz as well)

return oWindow;

}

This is the part that will call the refreshgrid...

and last maybe that you are using Page.ClientScript.RegisterStartupScript instead of ScriptManager.RegisterStartupScript or vice versa...

If you are already doing all this, please, post a 'working' sample so that somebody can check after you code...

Kind regards,
John.

Hi, John.
Yes. I want the grid to refresh after I have added a new record. When I put a break at the databind (after the record is added), I can see the added data in the radgrid.mastertablebview items.

I typed: ? radgrid1.MasterTableView.Items(2).Cells(6).Text into the immediate window (in Visual Studio), and got this result: "87456".
? radgrid1.MasterTableView.Items(2).Cells(4).Text
"1/27/2011 12:00:00 AM"

The grid is just not refreshing on the screen. I don't know how else to explain it.

I do have a addrecord.aspx page that has all the code you mentioned. I did change from clientscript.registerstartupscript to scripmanager.registerstartupscript, but that didn't make a difference.

Here's the code I have for that page:

<form id="form1" runat="server">

<script type="text/javascript">

function CloseAndRebind() {

GetRadWindow().BrowserWindow.refreshGrid();

GetRadWindow().close();

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz as well)

return oWindow;

}

function CancelEdit() {

GetRadWindow().close();

}

No no, I understand...

The ScriptManager.RegisterStartupScript thing did the trick for me. My problem was that the ajax event on the page was not triggered.

Can you confirm that your code goes trough the RadAjaxManager1_AjaxRequest after you close the page and that the rebind is called?

After that I would try to get your grid out of the table structure you have here just to make sure it does not interfere.

Also does the grid refresh after you click on a refresh command button you could add on the grid?

Does the grid refresh after you trigger a new postback on the grid page?

It looks like everything works fine just the grid does not seem to understand it should load the data it gets back.

Then last I would try to remove the ajaxmanager from the page to see if things are working when not ajaxified?

Can't you put a small project together and hand it over so I can try it on my side?

John,
Thanks for all your great questions. It really pointed me into the right directions. I tried pulling the grid out of the table, but that didn't seem to work. Then I wondered, is it because it's on a masterpage? I created a new page without a master, and copied all my controls and code to the new page. Worked like a charm.

I guess I have to do the ajax manager/ajax proxy thing. I was hoping to avoid that because I only need the ajaxmanager for the page itself. No other content areas need the ajax manager.

I'll let you know what gets the code to work.

Thank you again for the guidance!

John, thanks again for all the help.

Ok, so I got it to work. It did have something to do with master/content pages. The problem is, I have two content areas that both use the telerik script manager. I had to put that out on the Master page to prevent errors. The AjaxManager was hiccuping because it couldn't find that script manager. I had to put the AjaxManager on the MasterPage, and put a ajaxmanagerproxy to the content page.

My new issue is that my stylesheet is dropping for some reason. I'll get that working. However, that is not as relevant to this part of the discussion. Here's the code to make the master/content ajaxmanager happy:

MasterPage.aspx - just make sure your AjaxManager is loaded before the content, or else you will throw a null exception when the content script tries to find the Master's AjaxManager

Thanks but I did nothing. I had the time to check some options with you.

Can you post your radajaxmanager code from your asp? It should look like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<ClientEvents OnRequestStart="onRequestStart" />

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

You guys seem like your more knowledgeable than I! I'm having the grid refresh issue...go figure :) Database receives inserted record but expanded detail table doesn't show it unless I either set viewstate to false(that collapses detail grid) or manually expand and collapse detail table.

Problem fixed. Telerik you need better / easier documentation on the master / detail page, radgrid & detail table, insert record with a popup window. All the examples you have just couldn't quite get me there. Was so close, but just couldn't get the detail grid to refresh. Here is the forum (Telerik you have great forums!) that I used to solve the issue.

Hey guys,

I decided to post the solution to my problem. I was given this project and it contained both the RadAjaxPanel and RadAjaxManager. In the documentation it notes that using these together can cause problems here:

"If the same control is placed in a RadAjaxPanel as well as included in RadAjaxManager settings as an AJAXified control (i.e., it is AJAXified by both the RadAjaxPanel and RadAjaxManager),the RadAjaxManager's setting will not work."

It seems to be common sense but just in case someone is still having this issue, double check this. In my case, I just had to move my client-side radgrid rebinding to server-side withing my OnAjaxRequest method. I don't know if this will help anyone but there you go.

Hello Carlos,

Without a sample project replicating the issue it will be difficult to guess what might be causing the problem, but I would assume that it is related to the AJAX settings of the RadAjaxManager. With that in mind, please ensure that the button is included in the AJAX settings and that the button is set to update the RadGrid (or the windows that you are referring to).

You can also open a regular support ticket with a sample, runnable project demonstrating the problem, so we can debug it locally.
