Prevent row selection when click on a CheckBox cell in a row

[Tran Thanh Phong]

I implement a checkbox column in a GridGroupingControl & TablesOptions.ListBoxSelectionMode = SelectionMode.One. I want to check many records to do some business but just one row is selected at the same time. The row is just selected when I click on a cell in the column that is not the checkbox column. It means that when I click on a cell in the checkbox column, it is only the checkbox cell is checked and does not select the current row. So could anyone provide my a solution, please? Thank you!

Hi Customer, 

Thanks for your interest in Syncfusion products. 

We have already provided KB regarding the selection of records when clicking on CheckBox. Please make use of the below KB, 

KB Link: https://www.syncfusion.com/kb/5698/how-to-select-the-record-row-while-clicking-on-checkbox-cell 

In addition to that, If you want to select many records when clicking on CheckBox , set the ListBoxSelectionMode as SelectionMode.MultiSimple. Please make use of below code and sample for your requirement, 

Code snippet 

//To select many rows 

this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiSimple; 

 

//Invoke the events to select the rows based on the checkbox value 

this.gridGroupingControl1.TableControlCheckBoxClick += new GridTableControlCellClickEventHandler(gridGroupingControl1_TableControlCheckBoxClick); 

this.gridGroupingControl1.TableControlCurrentCellKeyDown += gridGroupingControl1_TableControlCurrentCellKeyDown; 

 

//Event customization for selecting CheckBox by clicking 

void gridGroupingControl1_TableControlCheckBoxClick(object sender, GridTableControlCellClickEventArgs e) 

{ 

    GridTableCellStyleInfo style = (GridTableCellStyleInfo)e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex); 

    Record currentRecord = style.TableCellIdentity.DisplayElement.GetRecord(); 

    //To select the current Row 

    currentRecord.SetSelected(style.Text == "False"); 

} 

 

//Event Customization for selecting CheckBox using SpaceBar 

void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e) 

{ 

    GridStyleInfo style= e.TableControl.CurrentCell.Renderer.CurrentStyle; 

    

    if(e.Inner.KeyCode== Keys.Space && style.CellType == GridCellTypeName.CheckBox ) 

    { 

        //Raise the checkbox click event while changing the checkbox value using the space bar 

        e.TableControl.RaiseCheckBoxClick(e.TableControl.CurrentCell.RowIndex, e.TableControl.CurrentCell.ColIndex,MouseEventArgs.Empty as MouseEventArgs ); 

         

    } 

 

}
