I have a text box column in the grid. I want to restrict the textbox to accept only Numeric values. I would also like to put a max length restriction on that column when edited.

Hi Deepa,

We appreciate your interest in SYncfusion Products.

TO restrict the textbox to accept only Numeric values .

This can be achieved by handling the TableControlCurrentCellKeyPress event of Grid GroupingControl. Please refer the code:

this.gridGroupingControl1. += new GridTableControlKeyPressEventHandler(gridGroupingControl1_TableControlCurrentCellKeyPress);

void gridGroupingControl1_TableControlCurrentCellKeyPress(object sender, GridTableControlKeyPressEventArgs e)

GridCurrentCell cc = e.TableControl.CurrentCell;
GridTableCellStyleInfo styleInfo = (GridTableCellStyleInfo)e.TableControl.GetTableViewStyleInfo(cc.RowIndex, cc.ColIndex);
if (styleInfo.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record
&& styleInfo.TableCellIdentity.Column.Name == "ID")
if (!char.IsNumber(e.Inner.KeyChar))
e.Inner.Handled = true;


Put a max length restriction on that column

Please refer the code:
this.gridGroupingControl1.TableDescriptor.Columns["ID"].Appearance.AnyRecordFieldCell.MaxLength = 3;

Please try this and let me know if this helps.
