Hello Experts,

Is there a way to not allow embedded images?

Allow first and remove after is also good but prevent in the first place is good

Thnx

Paging on Telerik WinForms

Hi,

We need to implement paging concept in the Telerik rad grid control for win forms. At present Telerik doesn’t provide paging in win forms. Is there a way to implement custom paging , provided it should honor the filtering within the grid.

Thanks,
Julian

Grid Lookup Column and Popup

I've attached a picture from an application that I'm trying to mimic, and I"m unsure how to do this with the GridView.

1) The ellipses lookup button on a column. Basically the same display functionality as the GridViewBrowseColumn, but rather than opening an OPenFileDialog, I want to open another WinForm that I'd pass data back and forth between.

2) The alert icon in the column - alerting the user that there is some information to be displayed.

Can anyone help by pointing me in the direction of a sample that has functionality like this, or offering some ideas on how best to accomplish? Currently, I have a command column that is performing the Lookup Function, but as the user moves columns around, it may not be in the correct place, so I don't think that's the correct path.

Cell KeyDown Event

Hi,

When I press 'F1' in a cell, I want to show a messagebox that include radGridView1 information. (ex, rows.count, columns.count etc.)

private void ShowMessage()
{
RadMessageBox.Show(radGridView1.Rows.Count);
RadMessageBox.Show(radGridView1.Columns.Count);
}

I know that a radGridView has KeyDown event, but I can't find KeyDown event of cells.

Please help me.

Thank you.

[Solved] Reset cell format

I have a GridView where I am changing the cell BackColor when the value is changed:

void TelerikGridView_CellValueChanged(object sender, GridViewCellEventArgs e)

{

if (e.Row.Tag == null)

e.Row.Tag = e.Column.Name;

if (!e.Row.Tag.ToString().Contains(e.Column.Name))

e.Row.Tag += e.Column.Name;

}

void TelerikGridView_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.Row.Tag != null && e.Row.Tag.ToString().Contains(e.Column.Name))

{

e.CellElement.DrawFill = true;

e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;

e.CellElement.BackColor = Color.Red;

}

else

{

e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local);

}

This is working as expected, now I want to add a "Reset" button, when I click on it I would like to reset or remove the format of all the cells that have been changed, how can I accomplish this?

Regards,

Alberto
