Persist Uploaded Files - PostbackTiggers Do Not Work

Hi,

I am trying to use radasyncupload and datepicker controls. I have PostbackTigger property set to Datepicker which does the postback.

At first, I uploaded a file using radasyncupload. I just set date to the datepicker control so it did postback that lost uploaded file at this time. I thought the file should be persisted during the postback

Please assist me with that.

Thanks,
Chi MIng

0x800a139e - Master Pages

Hi,

I'm developing a web site using .Net 4.5, recently upgraded telerik from Bin40 to Bin45.

I have a parent master page, a nested master page that is use by the child page with the issue.
the parent master page is a plain page (no telerik), the nested master page has telerik controls and contains the RadScriptManager, the child page uses the nested master page and its RadScriptManager.

Please let me know if you need more information. Thanks!

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.
