Partial Postback with EnableLoadOnDemand

I have a usercontrol with a radcombobox inside an update panel. I am using many of these user controls on a single page. EDIT: I've enabled load on demand for the combobox.

When I finish using one of these comboboxes and click outside (blur the combobox), it calls the correct usercontrol page_load and the correct validation (validation only for that control).

However, every time I enter a letter into the combobox, it seems to call ALL page_loads and ALL validations.

To recap, selectedindexchanged causes only the required page_loads and validations to fire. Loadondemand causes all page_loads and validations to fire. Its almost as if selectedindexchanged only causes a partial postback while loadondemand causes a full postback. NOTE: LoadOnDemand does not cause the panels to update, it only calls the incorrect page_load and validation.

FYI, I've got the updatemode for the update panels as conditional and children as triggers. Does loadondemand not register as a trigger for this update panel?
If so, how do I add loadondemand as a trigger to the update panel?
If not, then what do you think is the issue here?

P.S.: That was a very confusing post, I'm still not sure if I'm getting my point across. Please let me know if you need more information.

RadMenu ItemTemplate and Image Maps

I am trying to use an Image and Map inside of a RadMenuItem and I cannot get the image map click events to fire. If I pull the image and map code outside of the RadMenu, it works as expected? Any ideas?

Programmatically created grid throws error if AllowFilteringByColumn = true

I am using the latest Q2 release of 2013 .NET version 4.5.

I have a method that creates a grid programmatically. This method is called on Page_Init wherever it is used. Grid is created and works just fine as long as I do not add "AllowFilteringByColumn = true". Here is the body of the method:

RadGrid grid = new RadGrid();

grid.ID = "CustomViewGrid";

grid.AllowFilteringByColumn = true;

grid.AutoGenerateColumns = false;

grid.AllowPaging = true;

grid.AllowSorting = true;

grid.PageSize = view.PageSize;

grid.ClientSettings.Scrolling.AllowScroll = true;

grid.ClientSettings.Scrolling.SaveScrollPosition = true;

grid.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel( 500 );

grid.ClientSettings.Scrolling.UseStaticHeaders = true;

grid.ClientSettings.Selecting.AllowRowSelect = true;

grid.ClientSettings.Selecting.UseClientSelectColumnOnly = true;

grid.AllowMultiRowSelection = true;

grid.GroupingSettings.CaseSensitive = false;

grid.PagerStyle.Mode = GridPagerMode.NextPrevNumericAndAdvanced;

grid.MasterTableView.AutoGenerateColumns = false;

grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;

grid.MasterTableView.DataKeyNames = new string[] { view.TableKeyName };

return grid;

I have methods to create the columns, which are added to the master table view column collection:

GridBoundColumn column = new GridBoundColumn();

column.DataField = dataField;

column.UniqueName = dataField;

column.AllowFiltering = true;

column.CurrentFilterFunction = GridKnownFunction.Contains;

column.FilterControlWidth = Unit.Pixel(100);

column.ItemStyle.Width = Unit.Pixel(120);

column.HeaderStyle.Width = Unit.Pixel(120);

column.AutoPostBackOnFilter = true;

column.ShowFilterIcon = false;

return column;

The datasource on the grid is set as follows:

EntityDataSource dataSource = new EntityDataSource();

dataSource.ID = "CustomViewGridDataSource";

dataSource.EntitySetName = view.TableName;

dataSource.ContextCreating += dataSource_ContextCreating; // set the object context here since I am using code-first EF5.0

dataSource.Where = view.Filter;

grid.DataSource = dataSource;

Finally, the grid is added to an ASP Panel placeholder (happens in Page_Init).

I get the following error when having AllowFilteringByColumn = true:

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Attribute of Resource missing

Hi,

I have an application which implemented RadScheduler with server side code and doesn't involves any web service or WCF. I'm now trying to include extra attribute to the Resource so that I can display extra info on the resource header.

The code of adding attribute looks like this:

resource.Attributes.Add("JobTitle", "Software engineer")

Then in the RadScheduler_ResourceHeaderCreated event, I try to read the attribute with the code below:

jobTitle = args.Container.Resource.Attributes("JobTitle")

Unfortunately the attributes of the resource is empty and I couldn't figure out why, is there a known limitation or issue pertaining to this? Please shed some light.

Hi, is there any plan to make the RadMaskedTextbox work for Opera Mobile? It's extremely buggy, even when using the demos.

Also, Firefox mobile browser appears to have issues as well from what I hear from other team members.

[Solved] .hideTab() and .showTab() not recognised

I have an aspx page with a Splitter control.I have Sliding panels on the left and right hand side. The right hand side one is either hidden or shown dependant on a value in a hidden field. This works fine. I also want to hide/show some of the tabs also dependant on the value in a hidden field. My code is...

if (parseInt($('#hd_AC').val()) <= 10) {

$('#Radsplitbar2').hide();

$('#EndPane').hide();

alert("Read-Only");

} else if (parseInt($('#hd_AC').val()) == 20) {

$('#RadSlidingPane_IP').showTab();

$('#RadSlidingPane_BL').hideTab();

$('#RadSlidingPane_Disc').hideTab();

$('#RadSlidingPane_BU').hideTab();

$('#RadSlidingPane_UIS').hideTab();

$('#RadSlidingPane_CRA').hideTab();

alert("Read-Only with Internal Personnel");

} else if (parseInt($('#hd_AC').val()) >= 60) {

$('#RadSlidingPane_IP').showTab();

$('#RadSlidingPane_BL').showTab();

$('#RadSlidingPane_Disc').showTab();

$('#RadSlidingPane_BU').showTab();

$('#RadSlidingPane_UIS').showTab();

$('#RadSlidingPane_CRA').showTab();

alert("HR - Admin View");

} else {

$('#Radsplitbar2').hide();

$('#EndPane').hide();

alert("Access not recognised");

}

This code is run in the window.load() function. As I said the Radsplitbar2.hide() and EndPane.hide() when hd_AC.val()==10 works fine. When I test with hd_AC.val() ==20 then I get a javascript runtime error @ $('#RadSlidingPane_IP').showTab(); with an error message Object does not support this property or method. What have I done wrong?
