Greetings,

I have a RadGrid, RadAjaxManager, RadToolbar and RadHtmlChart present on a page.  The RadAjaxManager is configured like so (the ControlIDs are obviously named):


I am trying to update the chart when firing a grid-based custom command from javascript like so:


Basically, at the time of partial postback, the grid requests its data source, but the chart doesn't.  The chart only requests its data source when the page initially loads.  Perhaps I'm missing something obvious.  I greatly appreciate any suggestions.

Hi,

I'm having an issue with real time column resizing on a rad grid. 
I can actually reproduce the issue on your demo page here:

http://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/column-row-resize-reorder/defaultcs.aspx

Choose the No wrap for cell content and allow resize to fit options. 

Resize the postal code and address columns by moving them right so that the browser window horizontal scroll bar appears (screenshot 1).
Scroll the window completely to the right. 
Attempt to resize the postal code column to the left. 
The left hand side of the grid shoots to the right very quickly. 
In some cases like in  screenshot 2, the address column is lost. 
Sometimes the columns get reordered. 
 
I've seen it in all browsers.
 
 I know that in the grid on your demo it does not make sense to make the grid this wide. But in our own grids we have a lot more content so resizing to this type of width is necessary. 
 
 Would you have any suggestions to eliminate this issue?
 
 Thanks

All the multiple file upload examples I've seen upload the files as soon as they are selected, which is not what I need.  I need to allow the users to select the files first, then click the upload button.  This scrrenshot is an example of what I need:

Please let me know how to do this with AsuncUpload.  Thanks

Hi every body,

I have a <asp:ImageButton> that is supposed to force the browser to open "Save As" dialog box in attempt to download an image into the client machine.
The image was previously produced successfully in a previous process:

 Using bitmap As New Bitmap(188, 306)
            browser.DrawToBitmap(bitmap, New Rectangle(0, 0, 188, 306))
            Using stream As New MemoryStream()
                bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Png)
                Dim bytes As Byte() = stream.ToArray()
                myImage.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(bytes)
            End Using
 End Using

and is shown successfully within the <asp:Image> tag.


My Download ImageButton has the following code behind:

Private Sub imgbtn_Download_Click(sender As Object, e As ImageClickEventArgs) Handles imgbtn_Download.Click
        Dim bytes As Byte() = Convert.FromBase64String(myImage.ImageUrl.Split(",")(1))
        Response.Clear()
        Response.Buffer = True
        Response.Charset = ""
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
        Response.ContentType = "image/png"
        Response.AppendHeader("Content-Disposition", "attachment; filename=" + "abc.png")
        Response.BinaryWrite(bytes)
        Response.Flush()
        Response.End()
    End Sub

I noticed that if the <asp:ImageButton> was placed inside <Telerik:RadAjaxPanel> the "Save As" dialog box doesn't pop up and the consequently download process doesn't start. However, if I shift the ImageButton control out of the <Telerik:RadAjaxPanel> it works successfuly.

So is there any explanation from Telerik Team why such behavior is taking place. And is there any recommendation to make the "Save As" downlaod process succeeds while the <asp:ImageButton> is inside the <Telerik:RadAjaxPanel>?

Regards;

Hi,

I have a problem with my pivotGrid (last update of control)
My pivotgrid is connected to a multidimensionnal database and I would like to set in row zone a hierarchy.

this causes a shift of he columns zone which is displayed on the right of the grid, not aligned with the aggregated fields, as shown in the attached file.

is there something I can do with the properties of the pivotgrid to fix this display issue.

thanks in advance

Regards

Hi there

I am probably doing something really stupid or not understanding how to link up to the datasource properly but I have been working on this for a couple of days and I can't seem to work out how to get the rating to work with a datasource.

I have a stand alone rating control on my page that I wanted to link up to an  accessdatasource that would display the current rating.  (I also want to be able to allow users to rate using the same control and save the value into the database too, but that's another story)

Here is what I have


As you can see, the datasource is based on a query which works out how many times the album has been rated and what the average rating is already, (by counting times rated, adding up all the ratings and dividing the total ratings by the count of times rated, then by rounding to whole value)

All that displays though is one empty star (if I hover over it, it does display the average rating though)

I have looked at EVERY demo and documentation on databinding for the rating control but I just can't seem to get my head around what I should be doing.

Please, please, please point me in the right direction before I pull all my hair out and bite my nails down to the quick

Thank you in advance

Hi. i´m developing an web with telerik and need to know if user has drag any header to group filtering in a postback. I can use client side o server side code, there are any way to achieve this?

Hi

I am using Telerik Version  2013.2.625.40 , is the Batch Update Exist in RadTreeList ?.
This is clients requirement ,

Please let me know

Karthik.K

I am binding my grid dynamically on the client side with JSON data similar to this example http://demos.telerik.com/aspnet-ajax/grid/examples/client/livedata/defaultcs.aspx. However I cannot get paging to work.

There is no mention on this page http://www.telerik.com/help/aspnet-ajax/client-side-binding-specifics.html of any limitations with paging. I have 25 items in my datasource and the page size is set to 10. However my grid footer shows " Page 1 of 2, items 1 to 10 of 11. " when displaying all 25 items.

Do I need to specify anything else to get it to show the correct number of records?

hey guys need some help here as we're upgrading or trying to upgrade telerik controls from:
File Version 2010.1.519.35  to File Version 2013.3.1114.40

there's an issue in the rad Filter as it cannot find the ControlName which back then was "rfContextMenu" but now I have no idea.

if it references a different "default Name" for the controls, I could do a simple find and replace. can someone help me out here cuz I have a lot of "code behind" for 66+ filters for prerender, apply and item command that the program is dependent on .
thanks 
rik - below is the code behind that can't find "rfContextMenu"

 protected void WorkOrdersRadFilter_PreRender(object sender, EventArgs e)
        {
            RadContextMenu menu = WorkOrdersRadFilter.FindControl("rfContextMenu") as RadContextMenu;
            WorkOrdersRadFilter.RootGroupItem.Controls[2].Controls[1].Visible = false;
            menu.DefaultGroupSettings.Height = Unit.Pixel(250);
            menu.EnableAutoScroll = true;
            WorkOrdersRadFilter.Culture = Thread.CurrentThread.CurrentCulture;            renameFilter();
            var ctrl = ControlsOfType<ITextControl>(WorkOrdersRadFilter).Where(p => p.GetType() != typeof(LiteralControl));
            if (ctrl.Count() > 0)
                (ctrl.Last() as Control).Focus();
            foreach (var picker in ControlsOfType<RadDateTimePicker>(sender as Control))
            {
               // picker.SelectedDate = DateTime.Today;
                picker.DateInput.DateFormat = "MM/dd/yyyy";
                picker.DateInput.DisplayDateFormat = "MM/dd/yyyy";
            }
        }
