Greetings,
Here is a good example of how to use an Excel spreadsheet as the data source for a RadGrid...
http://www.telerik.com/forums/rad-grid-import-from-excel
Is there a way to modify this example to use a spreadsheet data source that was uploaded with RadAsyncUpload without saving the xlsx to the server first - like a file stream or something? Any advice or examples would be appreciated.
Thanks!
Matt

I have a pre-existing set of styles in use for an application I'm building and the RadMaskedTextbox creates a <div /> wrapper around the control, with
RadInput RadInput_Defaultin the class declaration for the div. Is it possible to remove these? They override some of my default styling, so I'd rather they just don't get attached upon render at all if possible. This is for version 2017.1.228.45.
Thanks!
Scott

Hi
Is it possible to change the maxjsonlength used by the jsonserializer in radimagegallery??
I sometimes need to load images temporarily by passing base64 string instead of url, but I get maxjsonlength error.
I have tried in web.config but that doesn't help.
Thank you for your help

Grid Column value changed to 0 when exporting Grid to Excel. Please see the following demo code, the value of "Freight" column changed to 0 when clicking the Export button, but as soon as I change the DataFormatString="{0}%" to DataFormatString="{0}", everything works fine when exporting. But I do need to display the number as percentage (no decimals) in my senario. Any help would be much appreciated!

Hi,
I have couple of textboxes being generated from a javascript function which passes the data to the kendo.template and the textboxes are generated dependng upon the data passed through the JS function. The textboxes have multiple page events such as onfiocus() and onblur(). These page events are getting fired mutiple times. I tried keeping a counter so that these executes only once, passed static data such as 0 and 1 for forcing them to execute once only and many other stuffs. None of them has worked, Is there any chance, this can be a bug in Kendo Grid or Kendo Template, because other kendo tools are not doing this. Please advise, how to proceed from here.
In the attached image the 7 TextBoxes has the above bug
Thanks in advance

Hi,
Could someone please let me know how to implement on click functionality of hyperlink which is inside a radgrid. Radgrid has been binded with datatable dynamically. Radgrid autogeneratecolumns has been given as true.
on click of hyperlink a command prompt should open and run the command as requested.
Asp.Net:
<telerik:RadGrid ID="radgrid1" runat="server" AutoGenerateColumns="true"
Width="100%" GridLines="None" CellPadding="0" AllowPaging="True" AllowSorting="True" OnItemDataBound="radgrid1_ItemDataBound"
PageSize="200" >
<PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>
</telerik:RadGrid>
C#:
protected void radgrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)
{
GridDataItem item = (GridDataItem)e.Item;
cmdArgument = item["command"].Text;
HyperLink link = new HyperLink();
link.Text = item["command"].Text;
item["accurev_command"].Controls.Add(link);
}
}

I have several comboboxes with checkboxes. I am setting their checked states from server side. The problem is I also want to append a comma at the end. How do I do that? What I've tried:
private void RestoreCheckboxCombobox(RadComboBox combobox, List<int> selectedIds){ List<RadComboBoxItem> selectedItems = new List<RadComboBoxItem>(combobox.Items.Count); StringBuilder sb = new StringBuilder(100); foreach (RadComboBoxItem itm in combobox.Items) { if (selectedIds.Contains(int.Parse(itm.Value))) { selectedItems.Add(itm); itm.Checked = true; sb.AppendFormat("{0}, ", itm.Text.Trim()); } } if (sb.Length > 0) combobox.Text = sb.ToString();}

Hi
I am having a master page-content page set up in my web application. One of the content page includes a RadGrid and a RadComboBox with MetroTouch skin. The RadGrid is ajaxified using the RadAjaxManagerProxy and the issue is, the RadComboBox is losing its default styling when the RadGrid initiates an Ajax Request.
This issue happens with the Metro, MetroTouch, & Silk skin and works fine with the Default, Web20 etc. Skins. You can view the unusual behavior here.
Here is the sample which illustrate the above mentioned issue.
Masterpage :
Content-page:
Since the RadGrid is ajaxified, how its affecting the RadComboBox? Is this a bug?
Thanks,
Vishnu.

As the title says, CheckedItems is empty. I have no idea what's wrong. As a workaround I am using Request.Form["<client id of the control"] (because they are there in the json). Any ideas?
