RadDropDownList in RadTreeView NodeTemplate

I discovered that RadTreeView findControl only works in finding Telerik controls in a NodeTemplate, but does not work when trying to find an ASP control embedded in a NodeTemplate. This forced me to change my NodeTemplate column from <asp:dropdownlist> to <telerik:RadDropDownList>. I dynamically add values to the dropdownlist server side in NodeDataBound (see code below). This worked great with <asp:dropdownlist> but with <telerik:RadDropDownList> there are several issues: 1) values aren't displaying in the dropdownlist, 2) it appears there is a dropdown behind a dropdown, 3) dropdownlist width is incorrect. I've attached an image showing RadTreeView using <telerik:RadDropDownList> versus <asp:dropdownlist>. I want the solution using <telerik:RadDropDownList> to look exactly as it does using <asp:dropdownlist>. Assistance in resolving this issue would be appreciated. We are using Telerik Runtime Version v4.0.30319. Thanks.

FIX: RadScriptManager compatibility issues with Ajax Control Toolkit

Problem: The RadScriptManager is incompatible with the Ajax Control Toolkit (Version number 40412 and higher).

The following error appears when controls from the ACT are present on the page:
Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.

Solution for .NET 4.0 projects: Upgrade the RadControls for ASP.NET AJAX version 2010.1.625 or newer.

Important: Make sure you use the .NET 4.0 build of both Telerik.Web.UI.dll and AjaxControlToolkit.dll

If upgrade is not option you can use the following workaround:

    
            <telerik:RadScriptManager runat="server" EnableScriptCombine="false" />

Solution for .NET 3.5 projects: Override the references to MicrosoftAjax.js and MicrosoftAjaxWebForms.js to point to the ACT script files.

    
            <telerik:RadScriptManager runat="server"> 
        
                <Scripts> 
        
                    <asp:ScriptReference Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" 
        
                        Name="MicrosoftAjax.js" Path="Scripts-40412/MicrosoftAjax.js" /> 
        
                    <asp:ScriptReference Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" 
        
                        Name="MicrosoftAjaxWebForms.js" Path="Scripts-40412/MicrosoftAjaxWebForms.js" /> 
        
                </Scripts> 
        
            </telerik:RadScriptManager>

The script files are obtained by building the ACT from source. Sample project, including the scripts for version 40412, is attached.

Items on RadGrid become to zero inside ItemDataBound only

Hi, I try to add new row to radGrid by this code (Add button)

PartDt.Rows.InsertAt(dr, 0);

dgdPart.CurrentPageIndex = 0;

dgdPart.DataSource = PartDt;

dgdPart.DataBind();

dgdPart.MasterTableView.Items[0].Edit = true;

dgdPart.Rebind();

After dgdPart.Rebind(); code step into

protected void dgdPart_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.IsInEditMode && e.Item is GridEditFormItem)

{

if (e.Item.ItemIndex > -1)

{

RadComboBox cmbPart = (RadComboBox)dgdPart.Items[e.Item.ItemIndex].FindControl("radcmbPart"); //Error line

....

}

I try to debug and see while e.Item.ItemIndex is 0 and the dgdPart.Items.Count is 0 at line "//Error line" so I got error "Index was out of range. Must be non-negative and less than the size of the collection."

I also found the dgdPart.Items.Count is 0 only in dgdPart_ItemDataBound, If I skip the erorr line above and continue until finish dgdPart_ItemDataBound, It comeback to dgdPart.Items.Count = 1

Could you suggest me to solve this problem? Thanks!!

GridDateTimeColumn DataFormatString not working from codebehind

Hi all,
I'm dinamically adding columns to my RadGrid.
I need to add a GridDateTimeColumn to show and allow the user change a time, so I need to display data in format HH:ss .
I am trying to do this using DataFormatString property but it doesn't work: I always see the standard format yyyy/MM/dd HH:mm:ss .

Here is my code:

GridDateTimeColumn col = new GridDateTimeColumn();
col.PickerType = GridDateTimeColumnPickerType.TimePicker;
col.DataField = "FIELD";
col.DataType = typeof(DateTime);
col.DataFormatString = "{0:HH mm}";
myRadGrid.MasterTableView.Columns.Add(col);

Can anyone help me?
Thanks in advance.

[Solved] RADCombobox Remember items even after .clearItems();. Not Displayed on Page. But Uploading on Postback,,Duplicate value Problem

                                        var comboItem = new Telerik.Web.UI.RadComboBoxItem();

                                        comboItem.set_text(heat_no[j]);
                                        comboItem.set_value(heat_no[j]);

                                        ddl_cast_no.get_items().add(comboItem);
                                    }

[Solved] Button doesn't work with asp:Panel DefaultButton property nor UseSubmitBehaviour is rendering submit input?

Hi,

I am trying to achieve a post back on enter key pressed. I found out that the RadButton's property UseSubmitBehaviour doesn't do anything? I would expect if this is true, the button to be actually a submit button and if false to be a normal button. This seems not to be true here.

As I found out this is not working out, I tried using asp.net control Panel and it's property - DefaultButton to see if it's going to help, but it didn't.

I am using the latest version of the telerik ajax controls library. How can I achieve autopostback on enter? I don't want to subscribe to keypress events and watch for enter key. This should be built in. How can RadButton render input[type=submit] instead of input[type=button]?

Thanks,

Ivan.

CrLf in EmptyMessage + Tooltip

Seems like if you have a multiline radtextbox with a multilined emptymessage (containing CrLf's) AND a tooltip, the emptymessage is set as the value of the textbox.

If only using Lf's to seperate the lines it is working as expected

generated html that is working (without Cr's):
<input ...... value="{"enabled":true,"emptyMessage":"EmptyMsg1\nEmptyMsg2","validationText":"","valueAsString":"","lastSetTextBoxValue":"EmptyMsg1\nEmptyMsg2"}">

generated html that is working (with CrLf's):
<input value="{"enabled":true,"emptyMessage":"EmptyMsg1\r\nEmptyMsg2","validationText":"EmptyMsg1\nEmptyMsg2","valueAsString":"EmptyMsg1\nEmptyMsg2","lastSetTextBoxValue":"EmptyMsg1\nEmptyMsg2"}">

I've manually fixed this by removing any Cr's from the EmptyMessage, but seems like a strange bug as it is only a problem when a text for .Tooltip is used.

[Solved] EditForm Calculated Textbox

On a custom edit form for a grid, I have two bound decimal fields.
I want to update a third calculated textbox when the user changes any of the two bound fields.

I followed Dimo's example from an old post called "ascx editform with calculation textboxes when onfocus or onblur", but I was never able to make it work.

Could someone take a look on the attached screen and give me an idea on how to do this? Thanks

--------------
Obviously, I am trying to update the "Total Cost" textbox, if the user changes the Quantity, or the Unit Cost textboxes, which are both bound to the database.
