Thank you for your interest in Syncfusion product.
If you want to verify the same value is there in a column of all rows in a grid. We have customized the sample as per your need. Please refer the below attached sample.
Sorry for the delay in response.
If you want to identify whether the same value is occurred on particular column (column as 3) or not, you can use the “Contains” method. And also if you want to separate the delimiter in the grid cellvalue, you can use “Replace” method. Please refer the below code,
private void button1_Click(object sender, EventArgs e)
if (checkBox1.CheckState == CheckState.Checked)
string s = cmbSearch.Text;
myArray = s.Replace(",", "").Replace(".","").Replace(" ","");
highlighttext.HighlightText = myArray.ToString();
for (int k = 1; k < this.gridControl1.RowCount; k++)
if (this.gridControl1[k, 2].Text.Contains(myArray))
this.gridControl1[k, 2].BackColor = Color.DeepSkyBlue;
this.gridControl1[k, 2].BackColor = Color.White;
Please let us know if I misunderstood your query.
