I'd like to display the first 30 or so characters of an nvarchar(max) field in my radgrid along with a "Read More ..." type link to display the rest of the datafield.

I'd like the link to either expand the rest of the column to a max width of a few hundred pixels or use javascript to put the data into a window of some sort.

Has anyone done with this before?  If so, please point me the right direction.  Thanks much.

If I click on node it will firing node click event. If I double click on node it will firing node click event. double click event is not firing. How can i slove this issue???????

Hello,

I have a radgrid on a page with a custom control as an edit form.

Within the custom control, there is a button which among other things it also adds a record to another radgrid on the same page (not the parent of the custom control). The button closes the custom control with <editedItem.OwnerTableView.ClearEditItems()>.

On which event I must include the rebind command of that second radgrid?

Is there an event which fires when an editform is closed?

 Thanks for your time...

As I'm sure that you will understand, I have spent hours attempting various methods of self-solving this issue, but haven't been able to get it resolved, and am hoping that someone can give me a hand with this.  

My edit form contains only one field that excepts data from the user.  Once that value has been entered, or edited, on TextChanged the other textboxes should be populated with values resulting from calculations.  Four grid values are used in the calculations.

 I need to access each of the four provided values, perform the calculations, and load the results in the text boxes in the edit form, allowing the user to save the changes to refresh the grid.

 THIS DID NOT WORK: ClientEvents-OnBlur="calculateNetCash"

function onBlur(sender, args) {

    var textBox1;
    var textBox2;
    var textBoxTotal = $telerik.findControl(sender.get_parent().get_element(), "RadNumericTextBox3");
    var total;
 
    // get reference to the other RadNumericTextBox controls here
     
 
    // calculate the total
     
    // set the value for the last RadNumericTextBox
    textBoxTotal.set_value(total);

}

WHAT'S WORKING.  I can obtain the value of txtCashIn using  onChange = calculateNetCash(this)  and the values necessary for performing the calculation, using:

 Protected Sub OnItemDataBoundHandler(ByVal sender As Object, ByVal e As GridItemEventArgs)
        If e.Item.IsInEditMode AndAlso TypeOf e.Item Is GridEditFormItem Then
            Dim editForm As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
            Dim commissionRate As TextBox = DirectCast(editForm.FindControl("txtCommissionRate"), TextBox)
            Dim a As String
            a = commissionRate.Text
        End If

 End Sub

  These are my best test scenarios.  I figured that I could use hidden fields and then JavaScript to access the values for calculations.  But have not found any method, after hours of searching and testing, to reference the text boxes in the edit form template to store the values.

THANK YOU

My List is displaying correctly and filtering correctly however when selecting item all that is selected is the type name ??
  

 Please tell me what I am missing or what to change?

Hi,

I have read this article that explains how to use ItemCreated to localize declarative grid column headers. I have tried doing this in Page_Load using the grid.Columns collection and it seems to work fine + it is easier to work with a GridColumn for setting HeaderText as I have access to the UniqueName and Filter Tooltip properties.

Is there any reason not to do this?

Good day,

I'm currently migrating some user controls to telerik to use the new features. One of our user controls was a image upload control. Basically it had an asp.net img object and a stardard asp.net file upload object.

I changed it for a RadBinaryImage and a RadAsyncUpload. So far, the changes have worked. But I encountered a problem. Due to the lack of validation that the old control had, users could upload any file even if it wasn't images (like pdf, .doc, etc). Of course, it was not displayed properly on the asp.img object but it didn't show any exception, just an "x" sign. With the new user control, when I'm navigating through the records in a table and the control encounters one with a byte array that doesn't correspond to an image, it throws the following exception: "ArgumentException: The provided binary data may not be valid image or may contains unknown header".

I've read several posts in the forum and I already know that this exception is thrown because of the invalid format of the file loaded and that's ok, but I wanted to take control of this error if it happens so I did the following changes in the user control (ascx):

 If there's any error when loading the bytes into the control I want to show instead a fixed image. The problem is that the catch block is never reached. It always do the try block entirely even if the data is in an incorrect format. The exception is thrown later in a uncontrolled manner by the form making the form crash.

What could I do to catch this error if it happens and achieve what I want? Thanks in advance for any help.

I'm new to Telerik. Quite liking the toolkit so far. I encountered some strange behavior I would like some help with.
I'm using Internet Explorer 11.0.19. This bug seems to only happen in that browser, and not on Firefox.

I have a RadEditor with the page load function to turn enable comments and tracking. The problem is after it is turned on, on page load, clicking on a dropdown toolbar item would not do anything, i.e. no dropdown options shown. Getting rid of the code seems to fix the problem, but I need to have the flexibility to turn off and on comments and tracking from code-behind, as I'd like to dynamically change the comments and tracking options depending on the logged in user.

The bug seems to only happen if the first thing I do after page load is click on the dropdown options. If I click on the RadEditor content pane, everything would work fine.

Other things I tried:
* Focus RadEditor on page load (Didn't work)
* Move the C# code of enabling the comments and track changes to RadEditor onload, and oninit (Didn't Work, still same problem)
