I can see that there is an option to link ImageList to RadTextBoxControl but there are no options to use the images of said ImageList. Am I missing something? I don't see any properties to mention the index of the ImageList.

I don't see a null text property for a textbox menu item. I need to be able to label the textbox and the null text feature would be perfect for a tight situation like this.

Thanks!

I have a CheckedDropDownList with the CheckAllItem enabled.  When I check or uncheck that item, I don't want the ItemCheckedChanged event to fire for all the other items in the list.  I want to handle the "All Checked" my self. Waiting for the control to spin through my list, which I could have 100's of items, takes a while, while I have other code running to process based on the items being checked or not.

 

TIA

Hi,

I managed to get the sets of categorical data points of the lines in the currently visible range (that has been zoomed and panned). Now I need to write excel file with Date (Category) in first column and for each series a column with series' visible values (from the visible range). Is there any direct way to get the datatable of the visible points to write it to excel, or I need to go point by point and write it to datatable one by one?

Good Morning,

I have a gridview that loads some info about products in an unbound manner. I am using paging so I load only a handful at a time to quicken the loading process(because it really takes a long time to load many lines at once since there are some image getting/network traffic involved). But when I use paging, the grid still takes forever to load all pages before being usable. Is there anyway to load pages on demand? By on demand I mean click on the number of a page and load only the items that show on that page.

What I tried so far:

foreach (ECommerceDTS.PRODUCTSRow row in eCommerceDTS.PRODUCTS.Skip(radGridView1.GridViewElement.PagingPanelElement.ZIndex * PAGE_SIZE).Take(PAGE_SIZE))
{
    productEcomm = new ProductEcommerce(row);
    listProducts.Add(productEcomm);
    i++;
}

This works wonderfully loading only PAGE_SIZE items. The problem is that it loads only the first page, and the grid doesn't show other buttons to go to page 2. Is there any workaround this? Maybe hardsetting the number of buttons to show even if there are no items loaded?

Another question: Am I right to assume that ZIndex of the PagingPanelElement means the index of the selected page?

 

Thanks in advance. Kind Regards,

Leandro

I use dgv.PivotGridElement.SelectRow(row) to select a specific row.  I now need to ensure this row is visible(displayed) to the user.
How do I now scroll to the specific row?  The radGridView control has a EnsureVisible function on the rowInfo class, but I'm not finding anything on the PivotGrid

I've tried PivotGridElement.ScrollTo() but it's not working for me.

Is this possible, how do I accomplish this?

I'm using release 2015.3.1104.40
Thanks

Hello,

I want to scroll the virtual grid to a specific row index.

The amount of row is know to the virtual grid by assigning it to this.radVirtualGrid1.RowCount.

So I thought it must be easy to scroll the grid to a specific row index programmatically.

But the usage of

    this.radVirtualGrid1.TableElement.RowScroller.ScrollToItem(rowIndex);

this.radVirtualGrid1.TableElement.ScrollTo(rowIndex);

did not work as expected.

What is the easies way to scroll the virtual grid to the desired row index?

Thank You!

Regardss

Ingo

I have a textbox menu item in a submenu that isn't triggering events after the user enters a value and either clicks on the TAB or Enter key. The Validating event isn't being called. 

I have the "causesValidation" property set and AcceptsTab set to False and AcceptsReturn set to False.

How do I get the validation event to trigger when the user clicks on Tab or the Enter key from this textbox?

 

Thanks!

Hello,

I've been having some issues getting and setting the Focus on a RadTextBox control.

What's the best way to do this? Use the .Focus or the .Select method to set it?

This forum contains some conflicting info:
1. http://www.telerik.com/community/forums/winforms/editors/radtextbox-focus.aspx => "In order to set the focus to a RadTextBox when the form is loaded, please call its Select() method"

2. http://www.telerik.com/community/forums/winforms/ui-controls/radtextbox-focus.aspx => "Yes, you can use the Focus method exactly as with MS textbox."



Which one of the following properties is appropriate to get the control with the current focus?
  • RadTextBox.Focused
  • RadTextBox.TextBoxElement.IsFocused
  • RadTextBox..TextBoxElement.TextBoxItem.IsFocused

Greetings,

Jan
