Hi there, I am doing Checking duplicates by using the following code in Normal Datagridview

    if (dgvwDtls.Columns[this.dgvwDtls.CurrentCell.ColumnIndex].Name == "Column2")
            {
                if (!string.IsNullOrEmpty(e.FormattedValue.ToString()))
                {
                    foreach (DataGridViewRow dgvwRw in dgvwDtls.Rows)
                    {
                        if (e.RowIndex != dgvwRw.Index)
                        {
                            if (e.FormattedValue.ToString() == dgvwRw.Cells["Column2"].FormattedValue.ToString())
                            {
                                MessageBox.Show(e.FormattedValue.ToString() + " is already entered", Classes.Gnrlprps._MsgCptn);
                                dgvwRw.Cells["Column2"].Value = string.Empty;
                                e.Cancel = true;
                                return;
                            }
                        }
                    }
                }
            }

But in sync fusion how to use foreach, i just tried like this
 GridCurrentCell cc = this.gdbgrDtls.CurrentCell;
            if (cc.ColIndex == 2)
            {
                if (!string.IsNullOrEmpty(this.gdbgrDtls[cc.RowIndex, cc.ColIndex].FormattedText))
                {
                    foreach (DataGridViewRow dgvwRw in dgvwDtls.Rows)
                    {
                        if (e.RowIndex != dgvwRw.Index)
                        {
                            if (e.FormattedValue.ToString() == dgvwRw.Cells["Column2"].FormattedValue.ToString())
                            {
                                MessageBox.Show(e.FormattedValue.ToString() + " is already entered", Classes.Gnrlprps._MsgCptn);
                                dgvwRw.Cells["Column2"].Value = string.Empty;
                                e.Cancel = true;
                                return;
                            }
                        }
                    }
                }
            }

Hi Venkata,

 

Sorry for the delay.

 

Kindly refer the below provided code snippet and sample  for validating the cell duplicates. We have prepared the code snippet similar to the one provided by you. In this code we have checked the values of a specific column with the current cell. Please let us know whether the given solution achieves your requirement.

 

 

void gridDataBoundGrid1_CellClick(object sender, Syncfusion.Windows.Forms.Grid.GridCellClickEventArgs e)

        {

            GridCurrentCell cc=this.gridDataBoundGrid1.CurrentCell;

            if (e.ColIndex == 1)

            {

                if (!string.IsNullOrEmpty(this.gridDataBoundGrid1[cc.RowIndex, cc.ColIndex].FormattedText))

                {

                    for (int i = 0; i < gridDataBoundGrid1.Model.RowCount;i++ )

                    {

                        if(e.RowIndex!=i)

                        {

                            if (this.gridDataBoundGrid1[cc.RowIndex, cc.ColIndex].CellValue.ToString() == gridDataBoundGrid1[i, e.ColIndex].CellValue.ToString())

                            {                                                  

                                MessageBox.Show(this.gridDataBoundGrid1[cc.RowIndex, cc.ColIndex].CellValue.ToString() + " is already entered");

                                this.gridDataBoundGrid1[cc.RowIndex, cc.ColIndex].CellValue = string.Empty;

                                e.Cancel = true;

                                return;

                            }

                        }

                    }

                }

            }

        }

 

Please let us know if you have any other concerns.

 

Thanks & Regards,

AL.Solai.
