When I paste clipboard data into a RadGridView cell without entering cell edit mode, the grid view automatically resets the scrollbar position to the top.  If I paste data while in cell edit mode, the scroll position does not change.

I need to be able to paste data without entering cell edit mode because I am typically pasting data into a range of cells, and not just a single cell.  How can I prevent the scroll position from changing when I paste data while not in cell-edit mode?

Thanks,

Brian

I had developed a Winform app with using Telerik RadGridview before.
All clients use it without any problem.
But a few days ago, a client called me and told that it crashes anytime when he/she clicked any row in gridview.

We haven't thought that it could be related to telerik dll because any other clients use it successfully...
So we made a thorough search on net and tried any cause/solution possibilities but it didn't work out.
Even, we made the client format the machine and installed the system fresh again but after a short time, it started to crash... 

The most interesting side of the issue is that it happens only whenever i click, double-click or select any row in radGridview...
it just crashes and try to close the app directly...

I use 8.0.0.0 version of Telerik components which is bought in 2008, i believe

The error is very odd! couldn't think any solution to overcome...

What can i do to work the app out? Urgent help, please???

The event log of the machine shows me the below error log:

Windows Error Reporting

So I have a RadGridView  that is bound to a "BindingSource." The bindingsource is populated using a SqlDataAdapter.
The data being pulled in has an auto-incrementing Identity Column (ID) as it's primary key. 

I have successfully bound the grid, I can edit records and successfully see the changes in the database. However when I add a record, the data is successfully added to the database, but in the grid the "ID" field shows a value of "0" instead of the actual new value. How do i refresh the grid to show the new information? 

Thank you!

Hi Telerik Support,


We are creating theme for our windows application so far we got most of the controls to work as per our requirement but now we are facing some issue for RadTextBox null text.

FYI, i have created this theme in Visual style builder. If possible then please provide help for visual style builder first. If its not possible in theme then code will also work.

I have attached image with this post. Please check it for reference to the problem.

In normal TextBox you can see text entered by me which is "not null text" and it is displaying properly. I mean padding on top and bottom is proper in it.
But when you check another textbox which is having null text i mean text which is coming as placeholder is not proper. if you will zoom it and see closely then you will find that bottom padding is low compare to Top padding.

Please help me to find a solution for this.

Thank You,
Elke

I want to change the
backcolor of a listViewDataItem, then later on, change it back to the standard
color (ie white if it's not selected or the standard selection color of it's
selected).

I'm using this code to change the backcolor:

previewedListItem.BackColor = Color.Gold
previewedListItem.BackColor2 = Color.Gold
previewedListItem.BackColor3 = Color.Gold
previewedListItem.BackColor4 = Color.Gold

and this code to change it back:

previewedListItem.BackColor = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor2 = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor3 = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor4 = Color.FromArgb(0, 0, 0, 0)

The problem is that once I've changed it back, if the user selects that item,
it stays white instead of showing the selection color. How can I change the
color back in a way that will still show the selection color if the item is
selected?

In the UI for ASP.Net, the drop down control has an option 'AllowCustomText' which seems to be what I need for the UI for WinForms.  My users want to be able to select an item from a drop down box or type in a value that is not in the list.  I do not want the value they enter to be saved in the list.  Right now, when I set the drop down to 'DropDown' (as opposed to DropDownList) the user can edit the text, but as soon as they tab off the cell, it replaces what they typed with the nearest entry in the drop down.

I have seen some threads that discuss solutions, but they seem so cumbersome and all of them have the typed in value being added to the drop list.

Isn't there an easier way to implement this functionality?  (I'm on UI for WinForms 2014 Q1)

This (to me) seems to be a bit of an odd one.

I have a RadTreeView, if I set the SortOrder to None,  then Drag'n'Drop features work .. as i'd expect.

If I set the SortOrder to Ascending;  then Drag'n'Drop appears to be switched off?


Am I missing something?   Is there a setting I need,  or do I have to either implement my own custom sorting or custom drag'n'drop?

Thanks
Brian.

Hi,

Is there a way to change a rowfont to Bold based on the criteria in the records?

Example: 
Where I have code "c2.RowFont.Bold = True", it gives me error that Property Bold is read only.

Private Sub SetConditions()
     Dim c1 As New ConditionalFormattingObject("Forecolor Black", ConditionTypes.Equal, "0", "20", True)
     c1.RowForeColor = Color.Black
     grd1.Columns("trd_typ").ConditionalFormattingObjectList.Add(c1)

     Dim c2 As New ConditionalFormattingObject("Forecolor Blue", ConditionTypes.Equal, "3", "", True)
     c2.RowForeColor = Color.Blue
     c2.RowFont.Bold = True
     grd1.Columns("trd_typ").ConditionalFormattingObjectList.Add(c2)

     grd1.TableElement.Update(False)
End Sub

I want to programmatically tell the grid when to show the [+] hierarchy expand button.  Can this be done or do all the rows have to have this enabled?

I have a databound master and a load-on-demand child.  My problem is that not all rows make sense to have this template shown.  Below is how I am approaching this now. 

GridViewTemplate template = new GridViewTemplate();
 template.Columns.Add(new GridViewTextBoxColumn("Account"));
template.Columns.Add(new GridViewTextBoxColumn("CRM Opp ID"));
 gvAttainment.MasterTemplate.Templates.Add(template);

template.HierarchyDataProvider = new GridViewEventDataProvider(template);
 this.gvAttainment.RowSourceNeeded += new GridViewRowSourceNeededEventHandler(gvAttainment_RowSourceNeeded);

...

void gvAttainment_RowSourceNeeded(object sender, GridViewRowSourceNeededEventArgs e)
{
            
            switch (e.ParentRow.HierarchyLevel)
{

case 0:
                        //Query DB for data and display here
                        GridViewRowInfo row = e.Template.Rows.NewRow();
                        row.Cells["Account"].Value = from DB
