change text in the cell

When I'm changing text in textbox - the value in the cell is changing too(at the same time). I use event

private void rtx_TextChanging(object sender, TextChangingEventArgs e)

{

RadTextBox rtb = sender as RadTextBox;

string title = rtb.Name.Substring(0, rtb.Name.Length - "textbox".Length);

this.radLabelElement1.Text = rgv.CurrentRow.Cells[title].Value.GetType().ToString();

rgv.CurrentRow.Cells[title].Value = e.NewValue;

rgv.CurrentRow.InvalidateRow();

}

where rtx - radtextbox

What event? I need to use to do the same thing for textboxes - when I change value in the cell the value in textbox changes too. I was trying to use CellValueChanged but it affects only after I press enter

Radgrid cell formatting problem

Hi Telerik,
I have assigned some cols as read only in the radgrid(radform) and i used cell formatting to apply colors like this by name:

DTURradGridView.Columns["dtuct0"].ReadOnly = true;

DTURradGridView.Columns["dtuct1"].ReadOnly = true;

DTURradGridView.Columns["dtuct2"].ReadOnly = true;

DTURradGridView.Columns["dtuct3"].ReadOnly = true;

DTURradGridView.Columns["dtuy"].ReadOnly = true;

if (e.CellElement.ColumnInfo is GridViewDataColumn)

{

if (e.CellElement.ColumnInfo.FieldName == "dtuct0" )

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct1")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct2")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuct3")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

if (e.CellElement.ColumnInfo.FieldName == "dtuy")

{

e.CellElement.DrawFill = true;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.LightSlateGray;

e.CellElement.GradientStyle = GradientStyles.Linear;

}

Then i want to hide/unhide based on the selection like this:

private void normalToolStripMenuItem_Click(object sender, EventArgs e)//Normal View

{

DTURradGridView.Columns["dtuct0"].IsVisible = false;

DTURradGridView.Columns["dtuct1"].IsVisible = false;

DTURradGridView.Columns["dtuct2"].IsVisible = false;

DTURradGridView.Columns["dtuct3"].IsVisible = false;

DTURradGridView.Columns["dtuy"].IsVisible = false;

}

private void advancedToolStripMenuItem_Click(object sender, EventArgs e) //Advanced View

{

DTURradGridView.Columns["dtuct0"].IsVisible = true;

DTURradGridView.Columns["dtuct1"].IsVisible = true;

DTURradGridView.Columns["dtuct2"].IsVisible = true;

DTURradGridView.Columns["dtuct3"].IsVisible = true;

DTURradGridView.Columns["dtuy"].IsVisible = true;

}

When i Click on Normal Mode function, it applies colors to other cols. This is really strange for me. Please help me, thank you.

Invoking of collectioneditor for property value in RadPropertyGrid

Hi,

We are trying to replace a winform propertygrid with a RadPropertyGrid.

Previously, we were binding an object to the property grid, which in turn was displaying all the properties. If one of the properties is a collection it used be displayed in a collectioneditor when invoked from the property value.

Since the Propertygrid is replaced by RadPropertyGrid, we have been unable to do this. Even when one of the properties is returning a collection it the property grid is not providing the means to invoke the collection editor. I feel like we are missing something.

Thanks in advance

What event fires when clicking "Click Here To Add A New Row"

When the "Click Here To Add A New Row" bar is clicked in a radgridview, I need to follow it with default column value entry.

What is the best way to default in values after the bar is clicked.

I have accomplished this with the right click New popup menu, but we would like to use the "Click Here to Add a New Row" bar as well.
