Adding dynamic datasource to dynamic Combobox''s in Grid Control

hi,

I have a grid Control, I would like to dynamically add rows(on a event) in a grid, in which two of the columns contain comboboxes, If i change the selection of one combobox, I would like to dynamically bind the other combobox (based on the selection). Could you please show hw this possible in the Syncfusion grid and give some pointers towards the same.

Thanks in Advance.

Hi Rahul,

If you wan to change the datasource for the specific cell based on some condition then handle the CurrentCellShowingDropDown event to place your new datatable directly into the GridComboBoxCellRenderer.ListBoxPart. This will affect the dropped cell datasource. Please refer to the attached sample for implementation and let me know if this helps.

Sample : ComboxDatasource.zip

Also refer the below KBs for more information.

hey Haneef,

Thanks a lot for your help, However I am a newbie to Syncfusion grid and would also like to know hw do I add a new row in DGBG?

Hi Rahul,

Thank you for your update.

Issue 1: showing AddNewRow..

If you want to to show the extra row( Addnew row ) in a grid, you can set the EnableAddNew property to True.

this.gridDataBoundGrid1.EnableAddNew = false;

Issue 2: adding a new row.

To add or remove rows in a grid, you just do it by working with the underlying datasource. The grid should automatically reflect the changes. Here is a code snippet that show this.

this.gridDataBoundGrid1.BeginUpdate();
DataTable dt = this.gridDataBoundGrid1.DataSourec as DataTable.
DataRow dr = dt.NewRow();
dr[0] = "NewRow";
dt.Rows.Add(dr);
this.gridDataBoundGrid1.EndUpdate();

Best regards,
Haneef
