[Solved] Threat a mouse Right-Button Click in the same way as a Left-Button Click?

Hi, my intention is to display a RadcontextMenu on a RadListControl when a mouse right-button is pressed or released (depending on the ClickMode configuration of the RadListControl).

I just would like to threat a right-button click in the same way as a left-button click is threated by default in a RadListControl, but I don't know whether Telerik provides a way to do this just by setting an specific property or somethins similar, what I'm doing is iterating the RadListControl items and determine which item contains the current mouse location but maybe this is a heavy method for big list item collections.

Pleasse. could you check my approach to see if it can be improved/simplified in some way via Telerik?

Also, I have an unsolved problem, in the line 96 of the code below I would like to determine which radListControl called the RadContextMenu to retrieve its SelectedItem.Text property, but I don't know if its possibly.

Thanks in advance.

[Solved] Radgridview cell validating

Hi,
I have 2 columns among other columns in a radgridview: one is a textbox and the another is a button (Scan button). The user either can enter data in the textbox or can click on the scan button to get back data into the textbox. The textbox has some validation that I don't need to be triggered if the user is clicking on the Scan button but should be triggered if the user click on any other cell. How can do that as right now any validation is triggered as soon as I click on the Scan button.

Thanks,

RadGrid Winform Refreshing Datasource

Hi, I recently installed the Telerik Winform and using the RadGrid control. I am working with a database where the values get updated every second and I have to display the updated rows to RadGrid. Before that I was using the standard DataGrid but there was lot of flicking problem on assigning the data source again to refresh it.

RadGrid is better option but I am still facing the same issue with it. I am using background worker control with Async mode queries and on Timer control I am refreshing the data
1. Clearing the dataset
2. RadGrid datasource to Nothing
2. Filling the dataset again,
4.and assigning the data source to RadGrid

All the above process causing the RadGrid to flick, can you please guide me to do this is better way. Example will be appreciated.

Thank you.

New row behavior

Hi,

I want to achieve the same 'new row behavior' as the default windows gridview.
That means that if I edit a cell in the 'new row', the row is also added to the datasource and is a 'real' row instead of a 'new row'. Now this only can be achieved by pressing enter or set the focus to another row.

Best regards

GridView

[Solved] RadButton base.OnClick problem

When I override Onclick on RadButton, the code first finishes the whole onclick method before firing base.OnClick.
For a standard Button, this works fine.
In the example below, the OnClick will first finish completely before the base.OnClick will be executed, but is should not.
How to fix this ?

public class QButton : RadButton
{
protected override void OnClick(EventArgs e)
{
var form = FindForm();
try
{
// set wait cursor
form.Cursor = Cursors.WaitCursor;

// execute base click code
base.OnClick(e);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
// set arrow cursor
form.Cursor = Cursors.Default;
}
}
}

Buttons, RadioButton, CheckBox, etc
