I have 3 combo boxes on a page, combo1, combo2 & combo3

the contents of combo2 are filtered by the selected value in combo1
the contents of combo3 are filtered by the selected value in combo2

I need to obtain the currently selected value in combo1 as an additional filter value for combo box 3 and was given an example involving a context filter.  This example is stuck in an endless loop.  heres the code for the combo

<telerik:RadComboBox ID="RadComboBoxCategories" Runat="server" Width="100%" OnClientItemsRequested="ItemsLoaded" OnClientItemsRequesting="ClientItemsRequesting"

onitemsrequested="RadComboBoxCategories_ItemsRequested" Skin="Default" EnableLoadOnDemand="true">

<CollapseAnimation Duration="200" Type="OutQuint" />

</telerik:RadComboBox>  <   telerik:RadComboBox ID="RadComboBoxType" Runat="server" OnClientSelectedIndexChanging="LoadGenres"     onitemsrequested="RadComboBoxType_ItemsRequested" Skin="Default"     Width="100%" EnableLoadOnDemand="true" AutoPostBack="False"     onselectedindexchanged="RadComboBoxType_SelectedIndexChanged">     <CollapseAnimation Duration="200" Type="OutQuint" />     </telerik:RadComboBox>

heres the javascript function

function ClientItemsRequesting(sender, eventArgs) {

var context = eventArgs.get_context();

var typeCombo = $find("<%= RadComboBoxType.ClientID %>");

context["FilterString"] = typeCombo.get_text();

}

  and the c#

protected void RadComboBoxCategories_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)

{

string temp = e.Context["FilterString"].ToString();

LoadCategories(e.Text, temp);

}

  the Itemsrequested event is being fired in an endless loop !

can you help ?  The LoadCategories method needs the value currently selected in the RadComboBoxType as part of the filter

If I have project which is using RadControls for .Net 2.0 before, what is the migration steps to use the controls for .Net 3.5?
- are all API functions identical between those two sets of controls?

Another question is what are the features differences between those two set of controls besides my list below?

- Net 3.5 Client-side Data Binding

- Entity Framework CRUD Operations

- LinqToSql CRUD Operations

- LinqToSql Manual CRUD Operations

Hello,

I would like to control with a slider a kind of chain. I would like to place a number of div-elements from left to right. Each div contain a picuture and a link and text. With the slider I want to be able to slide the different divs along the chain. Lets assumme the chain will contain 6 divs then i want to be able to see 3 of them on one time. I want to see div1, div2, div3. If i slide to the right i would like to see div2, div3, div4 and so one. Deepending on the zoom level I also want to be able to see more or less then 3 div-elements. 
I need a div-element because i want to change the background color of the different div-element according to events.

Does anyone have an idea how I can develop such a control?

I appreciate every help.

Cheers

Chris

Hi,

My upload control is located inside of an AjaxPanel, so I use the ConditionalPostback method.

When the user selects a file, I want it to immediately upload - how do I do this?

I presume I must use the OnClientFileSelected call, but I dunno where to go from here.

Thanks!

I have a nice presentation form that displays all the data within a table automatically (easily done with the component). However, now I want to be able for users to query the database table and click the query button and have the table updated.

Below is the code I am using:

EAIDataClassesDataContext db = new EAIDataClassesDataContext();
            var hl7dTypes = from p in db.REF_HL7_DATATYPEs where p.DATATYPE.Contains(RadTextBox1.Text.Trim()) select p;
            //LinqDataSource.Equals == hl7dTypes;
            //LinqDataSource.DataBind();
            //RadGrid1.DataSource = hl7dTypes;
            //RadGrid1.DataBind();
            RadGrid1.Rebind();

As you can tell I have tried the commented out options and all either do not work or cause a page rendering error. How can I get this to work?

I have set up a RadGrid (that is ajaxify) in a User control. This grid's data is bound dynamically and sometimes through the NeedDataSource event. The Script manager and AjaxManager is in the master page along with a RadTabStrip. I have an AjaxManagerProxy in the user control to ajaxify the grid.

The grid has the following properties:
-Columns are set statically
-Filtering is enabled on the first 4 columns only
-The last column does not have header information as it contains links about the details of each row in the grid
-Paging and sorting is enabled
-I have setup exporting through Excel (in ExcelML) and PDF
-Users can select rows.

Now, whenever I click on the header of a column to sort, ascending sort works. However, weird things start to happen:
-if I click the ^(up) arrow right next to the header text, the third column (2nd column down) gets sorted ascending.
-if I click the first column again, instead of descending sort, it stays in ascending sort.
-if I go down the rows sorting, as in if I click the first column to sort, then click the next column to sort, instead of the next column sorting, it is the next after next column that sorts. (I noticed that the Javascript indexes are changing, don't know why)
-paging to the next page stops at the second page, but that's not as bad as sorting.

I'll post my code when necessary. Any help will be much appreciated.

hi there, I have used ajaxRequestWithTarget for a button ajax event. I wish to pass argument to the button event and how would i get it out as a string?  for example, 

 

ajaxRequestWithTarget(

"btnRefreshAct", "RebindTask")

how would i get the RebindTask from the buttonclickEvent from Radajaxmanager?

 

 

Hi

I have a RadGrid with 5 function buttons. I want to hide / show these images on a row by row basis.

This is my Rad grid:

 

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="EditJobplan" Text="Edit JobPlan" ImageUrl="../App_Themes/Default/Images/JobPlanEdit_24.gif" UniqueName="Change"><HeaderStyle Width="1px" /><ItemStyle Width="1px" /></telerik:GridButtonColumn>

 

 

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="EditSession" Text="Edit Sessions" ImageUrl="../App_Themes/Default/Images/SessionEdit_24.gif" UniqueName="View"><HeaderStyle Width="1px" /><ItemStyle Width="1px" /></telerik:GridButtonColumn>

 

 

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Assign" Text="Assign" ImageUrl="../App_Themes/Default/Images/JobPlanAssign_24.gif" UniqueName="Assign"><HeaderStyle Width="1px" /><ItemStyle Width="1px" /></telerik:GridButtonColumn>

 

 

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Forum" Text="Forum" ImageUrl="../App_Themes/Default/Images/Chat_24.gif" UniqueName="Forum"><HeaderStyle Width="1px" /><ItemStyle Width="1px" /></telerik:GridButtonColumn>

 

 

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Preview" Text="Preview" ImageUrl="../App_Themes/Default/Images/Preview_24.gif" UniqueName="Preview"><HeaderStyle Width="1px" /><ItemStyle Width="1px" /></telerik:GridButtonColumn>

 

 

The code shows my ItemDataBound event, What is happening is that the entire column is being hidded / shown not the individual rows, what am I doing wrong?

Andy
