How to insert new blank row in gridgrouping control?

[Paurnima]

Hi,
I want to insert new blank row after multiple records are deleted from grid grouping control,
I am using ,
this.gridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordAfterDetails = true;
after Delete() but it doesn't work.
When I click on row it gives "Object reference not set to an instance of an object".
Is any solution regarding this?


Regards,
Paurnima.

Hi Paurnima,

 

Thank you for your interest in Syncfusion products.

 

If you want to insert a new blank row after multiple records are deleted in gridgroupingcontrol, you can enabled the “AllowNew” property as true. Please refer the below code,

 

Code:

 

private void buttonAdv1_Click(object sender, EventArgs e)

   {

     foreach (var tbl in this.gridGroupingControl1.Table.SelectedRecords)   // delete multiple record

      {

         tbl.Record.Delete();

      }

       this.gridGroupingControl1.TableDescriptor.AllowNew = true;           

   }

 

Please let us know if you have any concern.

Hello,
I tried the code but it can't help.
I am trying to delete multiple records at a time from grid grouping control using
  this.gridgroupingcontrol.TableModel.Options.SelectCellsMouseButtonsMask = MouseButtons.Left;
  this.gridgroupingcontrol.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;
  this.gridgroupingcontrol.TableOptions.AllowSelection = GridSelectionFlags.None;
And then want to insert new row in gridgroupingcontrol but it gives me object reference error.
Please give me any solution.

Hi Paurnima,

 

If you want to insert new blank row in the bottom section of the group, you can set the “ShowAddNewRecordAfterDetails” property  to true. Please refer the below code,

 

Code:

 

Suggestion 1 :

 

private void buttonAdv1_Click(object sender, EventArgs e)

        {

            foreach (var tbl in this.gridGroupingControl1.Table.SelectedRecords)

            {

                tbl.Record.Delete();

             

            }

               this.gridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordAfterDetails = true;

               this.gridGroupingControl1.TableDescriptor.AllowNew = true;

               this.gridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordBeforeDetails = false; 

        }

 

Please let us know if you have any concern.
