                                                                    CaptchaImage-RenderImageOnly="true" CaptchaImage-Width="219" CaptchaImage-TextChars="CustomCharSet"
                                                                    CaptchaImage-CharSet="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
                                                                    CaptchaImage-ImageCssClass="captchIMG" CaptchaImage-Height="36" CaptchaImage-BackgroundNoise="None"
                                                                    CaptchaImage-LineNoise="High" />

RADUpload InvalidFile Reason Code?

I saw a similar thread under RADControls, but didn't see any answer so I thought I'd post here. I have a RADUpload control placed on a page with AllowedFileExtensions set to allow ".doc,.docx,.xls,.xlsx,.zip,.txt,.csv,.pdf" and a MaxFileSize set to 15MB. I'm using client-side validation and have tested to ensure that invalid file types are being caught prior to form submission. My problem is that in uploading two, both valid, .xlsx files, one completes successfully and the other ends up in the InvalidFiles collection. I'm at a loss as to why one would work and the other not. Is there any way to access how a file fails to pass server-side validation?

[Solved] RadWindow & RadGrid Issue

hi

I have a Radgrid and a Radwindow. The radwindows is suppose to popup whenever one click view detail link in the radgrid. Well, it worked, but the funny part was that whenever i click the page in the radgrid, the windows popup itself. Why is that happening. Thanks and sorry if any inconvenience caused.

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand
Dim windowManager As New RadWindowManager()
Dim window1 As New RadWindow()

        If e.CommandName = "Select" Then
            Dim selectedRow As GridDataItem = DirectCast(e.Item, GridDataItem)
            Session("custid") = selectedRow.GetDataKeyValue("custid")
            window1.Width = "800"
            window1.Height = "520"
            window1.VisibleTitlebar = "false"
            window1.VisibleStatusbar = "false"
            window1.NavigateUrl = "~/custinfo.aspx?custid=" & Session("custid").ToString
            window1.ID = "RadWindow1"
            window1.VisibleOnPageLoad = True
            window1.ReloadOnShow = "true"
            ' Set this property to True for showing window from code
            RadWindowManager1.Windows.Add(window1)
            'Page.Form.Controls.Add(widnow1)
End Sub

Multiple Child Grids & Selecting Appropriate Row

I have three master /detail RadGrids like:

--1
----2
------3

I am trying to ensure two scenarios:

How can I make sure the appropriate rows are selected and the correct child data loaded for when the page loads and the user clicks a row in any grid?

I tried accessing the SelectedItems during Page_PreRender but only succeeded in selecting the first rows on page load, not when the user clicks a row. I tried the solution found on this site to always select a row but the code did not work for me.

[Solved] Is this possible in changing column of showing detail view ?

Hi all,

I am using RadGrid with NestedViewTemplate is another RadGrid for showing Master - Detail data. As the default, when you click on the icon in the first column to show the detail view.

Could I change this by clicking on another column (I don't want to use the first column and of course its icon).
Thank you,

radbutton popup is blocked

hello

i am currently replacing some buttons with the radbutton.
for buttons and linkbuttons i was setting the "onclick" attribute to call a JS-function which opens a popup after checking if it isn't already open which should be avoided when using radbutton.
so i adapted the code to use the radbuttons OnClientClicking property to

"function(sender,args){" + javaScriptCall + "}";

where javaScriptCall calls the JS-function which returns a window:

top.Popup1 = OpenWindowWithCheck(top.Popup1, 'url', 'errormessage','Popup1')

and here is the function:

function OpenWindowWithCheck(Window, PagePath, ErrorMessage, WindowName)
{
    if (Window == null || Window.closed) {
        Window = window.open(PagePath, WindowName);
    }
    else {
        if (confirm(ErrorMessage))
        {
            Window.close();
            Window = window.open(PagePath, WindowName);
        }
        else
        {
            Window.focus();
        }
    }
    return Window;
}

This works well except that i get a popup-blocker message by IE9 now.
How can i avoid this popup-message or is there another way to call my JS-function with radbutton?
