Hello, Jay, RadGridView
offers a convenient way for showing tool tips for the cell elements when they are not being edited: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/tooltips
Once an editor is activated, it handles the keyboard and mouse input. That is why the cell's tooltip is not shown.
The following code snippet demonstrates a sample approach how to show a tool tip when a RadTextBoxEditor
is initialized. The attached gif file illustrates the achieved result. Note that this is just a sample approach and it may not cover all possible cases. Feel free to modify and extend it for the other editor types in order to achieved the desired custom behavior.
this.radGridView1.CellEditorInitialized += radGridView1_CellEditorInitialized;
this.radGridView1.CellEndEdit += radGridView1_CellEndEdit;
private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
private void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
RadTextBoxEditor tbEditor = e.ActiveEditor as RadTextBoxEditor;
if (tbEditor != null)
if (toolTip == null)
toolTip = new RadToolTip();
toolTip.InitialDelay = 0;
RadTextBoxEditorElement elementUnderMouse = tbEditor.EditorElement as RadTextBoxEditorElement;
if (elementUnderMouse != null)
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
