Hi, I'm having two issues and I suspect at least one of them is dead-simple and caused by me making a simple mistake with me AutoCompleteBox in the EditItemTemplate of a GridTemplateColumn.

First problem; When I enter edit mode for a grid row, the AutoCompleteBox is empty rather than displaying the value that showed in that column before it entered edit mode. (I can "<%#DataBinder.Eval(Container.DataItem, "PartNumber")%>" in the EditItemTemplate to get the text to show up under/over the but that's not a solution.

Second problem; The AutoCompleteBox (set to single selection mode and text input) was appending a semicolon to the selected value. So I tried setting Delimiter="" which got rid of the unwanted character, but then it messed up the auto-complete functionality. Once that change was made, the drop-down options would appear if I paste a string into the box all at once, but not ever if I just typed the same string in. So, either: what's the right way to eliminate the semicolon, or how do I make the autocomplete function work right with delimiter set to an empty string? (I could theoretically trim the semicolon when I'm setting the value of the parameter before updating the DB, but that's a terrible solution since I might theoretically want semicolons in the PartNumber at some future date.)

                        <telerik:GridTemplateColumn UniqueName="PartNumber" HeaderText="Part Number" ItemStyle-CssClass="editWidth" 
                                FilterControlAltText="Filter PartNumber column" FilterControlWidth="85%">
                            <ItemTemplate><%#DataBinder.Eval(Container.DataItem, "PartNumber")%></ItemTemplate>
                            <EditItemTemplate>
                                <telerik:RadAutoCompleteBox runat="server" ID="racbPN" DataSourceID="ItemIdSource" DataTextField="IMA_ItemID" 
                                    HighlightFirstMatch="true" InputType="Text" TextSettings-SelectionMode="Single" MaxResultCount="200" MinFilterLength="4" 
                                     Delimiter="" DropDownHeight="300px" DropDownWidth="200px">
                                </telerik:RadAutoCompleteBox>
                            </EditItemTemplate>
                            <HeaderStyle Width="190px"></HeaderStyle>
                        </telerik:GridTemplateColumn>

Thanks for your time!

I am using the telerik ajax controls with an asp.net 4.0 website.  The default page is using the radajaxmanager control.  The page also has two radcombobox controls.  Server side OnItemsRequested events are used to populate the rad combo box controls.  A rad multipage control is also on the page.  Each page in the rad multi page displays rad grids based on the selections for the two rad combo box controls.  Session state is used to store the selections from the two radcombobox controls.  Object datasources use these session variables to populate the grids.

The problem is that a user can leave the website without closing the browser and then return to the website using a back button or favorite item.  The combo boxes to not show the previous selections.  However, the grids use the session variables to display the data.  I have been unable to set the radcombobox values.  It appears that th page load event does not fire.

I cannot remove the rad ajax manager because a tab strip control is also used.  The page needs javascript methods to control the tabs.

Do you have any suggestions?

I would like to create the diagram that

• User can drag & drop the item (Image) into the diagram.
• User can create the connection to link each item.
• User can save the diagram into JSON.
• User can load the diagram from JSON
  

Now, I can archive the first, second and third requirements. However, I have the problem when I try to load data from JSON. The Images are missing, and the connections also lost. I try to solve the problem by using 'visualTemplate' by setting '<ShapeDefaultsSettings Visual="visualTemplate" />', but it breaks my diagram instead. I have attached my code below.

This is my drag & drop event

function setDropTargetOnDiagram(element) {

     $telerik.$(element).kendoDropTarget({

          drop: function (e) {

               var draggable = e.draggable,

                    element = e.dropTarget,

                    diagram = element.getKendoDiagram();

 

               if (draggable && draggable.hint) {

                    var item = draggable.hint.data("data"),

                         offset = draggable.hintOffset,

                         point = new kendo.dataviz.diagram.Point(offset.left, offset.top),

                         transformed = diagram.documentToModel(point);

 

               item.id += "_" + generateUUID();

               item.x = transformed.x;

               item.y = transformed.y;

 

               var shape = createCustomShape(item);                               

             diagram.addShape(shape);

               }

          }

     });

}

 

function createCustomShape(item) {

     var shape = new kendo.dataviz.diagram.Shape(item);

     var image = new kendo.dataviz.diagram.Image({

          source: "../Images/Diagram/" + item.content.ImageName,

          x: 0,

          y: 0,

          width: item.width,

          height: item.height,

          stroke: {

               width: 0

          }

     });

     var textBlock = new kendo.dataviz.diagram.TextBlock({

          text: item.content.CustomText,

               color: "#000",

               fontSize: 12,

               x: item.content.TextX,

               y: item.content.TextY

     });

 

     shape.visual.append(image);

     shape.visual.append(textBlock);

 

     return shape;

}

This is my dragItem

This is the code for Save and Load JSON

This is my saved JSON

However, after I loaded the saved JSON, it was changed to be like this. (I lost the showing images, and connection is blank)

I try to solve the load JSON problem by using "visualTemplate" like this, but it breaks the diagram

Hello,

I'm using a Masterpage with .NET 4.0 and a RadSkinManager. Without obviously changing anything in the masterpage, I'm getting a NRE in one of my 3 content pages. The question is why is this only happening in one page and how to get RadSkinManager applied continously to all content pages?
My masterpage head is the following:

The error:

Hi all,

I am dynamically generating a RadGrid from code behind, which was perfectly working of retrieving the RadGrid Item data for hidden columns.

But, now I need to upgrade telerik version from "2011.1.413.35" to "2014.3.1209.35".

After doing this upgrade, the above method of retrieving the RadGrid Item data for hidden columns is not working, in other ways I am getting &nbsp; in place of the value.

Here is my sample code to create grid:
I am putting xmldatasource to fill the RadGrid.

radGrid.MasterTableView.Columns.Add(_CreateColumn("ID", "", Unit.Percentage(0), false));

private GridBoundColumn _CreateColumn(string dataField, string text, Unit width, Boolean readOnly)
    {
        GridBoundColumn boundColumn = new GridBoundColumn();

        boundColumn.DataField           = dataField;
        boundColumn.HeaderText          = text;
        boundColumn.SortExpression      = boundColumn.DataField;
        boundColumn.HeaderStyle.Width   = width;
        boundColumn.ReadOnly            = readOnly;
        boundColumn.Visible             = (width.Value == 0 ? false : true);

        return boundColumn;
    }.

Sample code to retrieve item value:
RadGrid radGrid = (RadGrid)control;
foreach (GridDataItem grdItem in radGrid.Items)
{
     string ID = grdItem["ID"].Text;
}

But the ID = &nbsp;   which should be some value which I filled though xmldatasource.

Please provide some bunch of code or any kind of help will be appreciated.

Hi,

I am using a RadTreeList control and I want to set the selected property (checkbox) of a row, depending on a value from the datasource.
This is my code:




However, when I run my page, I get an error on the line 'item_set_selected(true)' :


What am I doing wrong?

Hey !

I want to create a filter Template in Code Behind, but it's hard for me, can you help me ?

I would like to be able to filter the names of technicians with a combobox !

This is my code :





I see in your demo, you can create a filter with a radcombobox but its in XML :

I have a gridview with column name "Domain"

BY default it shows a single filter att one time but i want multiple filter in one time in single column

My RadGrid Structure is this

DOMAIN
@yahoo.com
@gmail.com
@india.com


I want to filter domain other than @yahoo.com and @gmail.com

How to do that in RadGrid Filter ??
