I have a "RadGrid" for Editing Data.

I have filtering enabled.

I perform validations using the "RadInputManager".

When I try to update the data happens to me what I show in the picture attached.

How I can solve this?

I add the code "aspx" to show the example:

Hi

Some of my users need to export to excel a huge quantity of information, 40.000 records or more.

i have two problems

1) The operation takes a lot of time (6 minutes or even more). How can i develop a timeout?

2) In my production server an exception is being triggered. But i cannot reproduce that exception in my development environment, so i don't know where to catch it. Below is a copy of the error i'm getting in the production server.:

Could you help me with this?

Hi

I have added dynamically at runtime "GridTemplateColumn" from code behind that column type checkbox how will do this

then when i click button control i need find control for checkbox 

On our web solution, using the editor, in chrome, a tab inserts this:

<p><span class="Apple-tab-span" style="white-space: pre;"> </span></p>

not an issue, but if you immediately press (delete), the html is changed to:

<span class="Apple-tab-span" style="white-space: pre; color: #56585a; font-family: Arial, Helvetica, sans-serif; font-size: 0.8em; background-color: #93bfd9;">

It's like the tab delete sequence triggers some type of macro. 

Anyone seen anything like this? And have a potential solution?

Thanks,
Todd.

Hi all,

I'm encountering some strange behavior using RadImageEditor.

I have code that displays two images on a page.  This in itself works fine.  However, attempting to resize the image on the server side causes the first image to not display at all, and the second image to not change its size upon display, though stepping through the code and looking at the properties indicates the Height and Width values are changed as expected.  Anyone have an explanation for this behavior?  Code included below.

Thanks in advance for any insights!

--Randy


            try
            {
                RadImageEditor1.ImageUrl = PathToUrl(imagerelpath);
                Telerik.Web.UI.ImageEditor.EditableImage ei = RadImageEditor1.GetEditableImage();
                ei.Resize((int)(ei.Width * .5), (int)(ei.Height * .5));  // browser rendering works as expected (shown full size) without this line
                RadImageEditor1.Height = ei.Height + 58;
                RadImageEditor1.Width = ei.Width;
            }
            catch (Exception ex)
            {
            }

            try
            {
                RadImageEditor2.ImageUrl = PathToUrl(backuprelpath);
                Telerik.Web.UI.ImageEditor.EditableImage ei2 = RadImageEditor2.GetEditableImage();
                ei2.Resize((int)(ei2.Width * .5), (int)(ei2.Height * .5));  // browser rendering works as expected (shown full size) without this line
                RadImageEditor2.Height = ei2.Height + 58;
                RadImageEditor2.Width = ei2.Width;
            }
            catch (Exception ex)
            {
            }

I have created a radgrid that functions with edit inplace and updates from an outside button to update an receords that were changed.  
I also would like to use the insert button to be able to add a new record. 
I am running in to a problem with the dropdowns because on an insert there is not a value to 'bind/eval', I need the dropdown to say "select' or something similar.  
Can I combine both items in the way I am trying?  I've attached the aspx from my column.  
Please advise.

                        HeaderText="Part Number"  ReadOnly="false" ItemStyle-VerticalAlign="Top" Visible="true" >

Hi

     How can I use a Rad grid to perform batch edit, Edit form and Pop-Up edit combined?

     I have a grid which uses batch edit with some drop down, check box and text box control. I want to use Edit form to edit and display another grid (which is                related to the individual rows in the first grid) by clicking on one button similar to the edit button. Also I want to show a pop-up to display and edit other related          data with the first grid on clicking on another button. How can i achieve this?

Thanks & Regards

Hello,

I have a RadGrid, this RadGrid uses an Edit Form Template containing multiple controls for user input. In particular, I am interested in how I can add existing values to a RadComboBox which has multiple checkbox options when the edit form is opened.

Currently, I have methods to get all the values I need to check from my database. I also have all other elements in the grid initialized on edit mode because they are bound in my markup. Below is the code I am trying to use to check some items in the RadComboBox (OnEditOrInsertMode handles RadGrid.OnItemCreated, getFormFactorIds is a function that returns a list of ids to be checked.):



But, this seems to have no effect when I verify that a particular item has values marked in the multiple select combobox, and step through the code in the debugger and watch the 'Checked' values be set to 'true'.

What is causing the 'Checked' values to be set back to false?
Am I setting the 'Checked' values in the correct handler?

Thanks

Hi,

I want to hide the text under control (check the attached image file).

And I want to get "SaveSettings" values like json/xml format. Is it possible?
If possible I want take them from javascript, but if it is impossible I want to know how to get this settings from code behind in xml or json format
