Hello Abdul,
Thank you for writing back.
The RadGridView.
AutoSizeRows property controls whether row's height in a
RadGridView will expand for multiline cell text. However, note that when a cell is in edit mode and you are typing in the editor, this value is not committed to the cell yet. That is why the row's height is not updated. You can find below a sample approach that demonstrates how to disable the rows auto sizing when the editor is activated and the row's height is adjusted by the
MinHeight property:
public RadForm1()
{
InitializeComponent();
this.radGridView1.Columns.Add("Text col");
this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
this.radGridView1.AutoSizeRows = true;
this.radGridView1.Columns[0].WrapText = true;
this.radGridView1.CellEditorInitialized += radGridView1_CellEditorInitialized;
this.radGridView1.CellEndEdit += radGridView1_CellEndEdit;
}
private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
{
this.radGridView1.AutoSizeRows = true;
}
private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
this.radGridView1.AutoSizeRows = false;
RadTextBoxEditor tbEditor = e.ActiveEditor as RadTextBoxEditor;
if (tbEditor != null)
{
tbEditor.Multiline = true;
tbEditor.AcceptsReturn = true;
RadTextBoxEditorElement el = tbEditor.EditorElement as RadTextBoxEditorElement;
if (el != null)
{
el.TextBoxItem.TextBoxControl.TextChanged -= TextBoxControl_TextChanged;
el.TextBoxItem.TextBoxControl.TextChanged += TextBoxControl_TextChanged;
}
}
}
private void TextBoxControl_TextChanged(object sender, EventArgs e)
{
HostedTextBoxBase tb = sender as HostedTextBoxBase;
if (tb != null)
{
this.radGridView1.CurrentRow.MinHeight = tb.Lines.Length * 16;
}
}
Note that this is just a sample approach and it may not cover all possible cases. Feel free to modify it in a way which suits your requirement best.
I hope this information helps. If you have any additional questions, please let me know.
