hey - i have a custom filter for combox in a telerik filter that i'd like to be typeable.
it's built in to the other radComboboxes:
can you suggest anything that i could use to make this possible - below is part of that initialize of the class:
i tried using [comboBox.EnableLoadOnDemand = true;] - but i dont know how to refernce the Object DataSouce to pick what's being typed in the filter ComboBox.
mark up is included:

<telerik:RadFilter ID="InventoriesRadFilter" runat="server" Skin="WebBlue" ShowApplyButton="true"

OnPreRender="InventoriesRadFilter_PreRender" OnApplyExpressions="InventoriesRadFilter_Apply"

ApplyButtonText="Filter Inventory" OnFieldEditorCreating="RadFilter_FieldEditorCreating" OnItemCommand="InventoriesRadFilter_ItemCommand">

<goldcustom:RadFilterComboBoxEditor DataSourceID="GetCustInvODS" FieldName="OWNER_COMPANYNAME" DisplayName="Owner Name" ComboBoxSkin="WebBlue" ComboBoxWidth="350px"

DataType="System.String" />

</FieldEditors>

</telerik:RadFilter>

THE ODS [need somehow to get what's typed in the RadFilterComboBoxEditor above

public DataTable getCustForInventory()

{

DataTable dt = new DataTable();

int[] myLoc = DivisionIDArray;

using (InventoryBC ibc = new InventoryBC())

{

dt = ibc.GetCustomerForInventory(myLoc,

"" );

return dt;

}

THE CLASS:

public override void InitializeEditor(Control container)

{

comboBox =

new RadComboBox();

comboBox.ID =

"ComboBoxEditor" + FieldName;

comboBox.DataSourceID = DataSourceID;

comboBox.OnClientSelectedIndexChanged =

"clientSelectedIndexChanged";//changes focus to the default button of the page

comboBox.OnClientLoad =

"clientSelectedIndexChanged";//changes focus to the default button of the page so, 1st item in the list can be selected

comboBox.DataTextField = (

String.IsNullOrEmpty(DataTextField)) ? FieldName : DataTextField;

comboBox.DataValueField = (

String.IsNullOrEmpty(DataValueField)) ? FieldName : DataValueField;

comboBox.Skin = ComboBoxSkin;

comboBox.Width = ComboBoxWidth;

container.Controls.Add(comboBox);

}

Radchart only changing skins once

I'm currently working with a number of RadCharts and a RadGrid. When a RadChart is clicked I switch its skin from black to deep red to show that it has been selected. This functionality works just fine. When one of the other charts is clicked a message is broadcast to all other charts to change their skin back to black if they were deep red. The line of code is called and the variable RadChart1.Skin is set to black, but the appearance of the chart maintains the deep red skin. If I set "SkinsOverrideStyles" to true the chart does change correctly, but it changes my legend back to SeriesName rather than ItemLabels (as well as changing a few other things I have set) so that solution doesn't seem plausible. Is there any reason why the chart would only correctly change skins once? As I previously stated even with SkinsOverrideStyles set to false it makes the change from Black to Deep Red without any problems, the issue is when I try to switch back from Deep Red to Black.

image manager page loaded but not buttons working

Hi,

Just upgraded radeditor to the latest version from an very old version (.net 1.1 site), now my site is running on .net 4.0, I have removed all the old telerik dll files and new rad editor seems working fine, I can edit/save the content, however, when I open the image manager from rad editor, image manager page is loaded, and the default folder in image manager is correct, I can see the sub-folders, but I can't see the (image) files, although it does say 'items 1 to 100 of 101', also none of the buttons is working on image manager page...

any help would be appreciated!

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.

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.
