This document provides steps to change the color of rows in a GridView based on certain conditions: 1. Drag and drop a GridView onto a page and connect it to a database table. 2. In the GridView's RowDataBound event, check each row's status value. 3. If the status is "Rejected", set the row's back color to orange. If the status is "Accepted", set the back color to green. This allows drawing attention to rows with different status values by displaying them in distinct colors.

1. Change the Colour of the Gridview Row Basedon Some Condition
See the following GridView
In the above GridView, you can see the data displayed in simple form with alternative rows
highlighted in Grey colour. Sometimes, you need to draw attention of users by highlighting
some of the rows in different colours, say all rows where status=’Rejected’ to be shown in
Red colour and in “Green’ colour where status =’Accepted’ etc.
Let us see step by step ways how to implement the above in a GridView.
1. As usual drag and drop a GridView and connect it to a backend database table.
2. Left Click on the GridView. From the Properties window, click on Events Button.
Shown in the below picture.
3. After this, Double click on ‘RowDataBound’ event. Shown below
4. Once you double click on the RowDataBound, the system automatically switch-over
to ‘Source’ mode. Between Protected Sub Gridview1_RowDataBound …. and End
Sub, add the following codes.

2. Protected Sub GridView1_RowDataBound(sender As Object, e As
GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
Dim rowValue As String = DataBinder.Eval(e.Row.DataItem, "Status")
If InStr(rowValue, "Rejected") Then
' colour the background of the row Orange
e.Row.BackColor = Drawing.Color.Orange
End If
End If
End Sub
5. Run the program and see the background colour changed to Orange in all the rows
whose status=’Rejected’. Display of my GridView is as below.
6. In the above source code, ‘Status’ is the column name of the backend database table
and ‘Rejected’ is the value in that column. You can replace these with your actual
table’s column name and data in that column.
7. In case, your backend table contains a mixture of uppercase and lowercase letters
like ‘REJECTED’, ‘Rejected’ or ‘rejected’, then covert the values into uppercase (or
lowercase) and compare. Source code for converting into uppercase and comparing
the same is given below:
Dim rowValue As String = DataBinder.Eval(e.Row.DataItem, "Status")
rowValue = rowValue.ToUpper
If InStr(rowValue, "REJECTED") Then
' color the background of the row Ornage
e.Row.BackColor = Drawing.Color.Orange
End If
Convert into
uppercase

3. 8. Now, let us see how to highlight some rows in another color based on the data they
contain. For example, if you want to display all rows with value ‘Accepted’ in Green
colour, add the below lines to the above souce (highlighted in Yellow colour).
1. Dim rowValue As String = DataBinder.Eval(e.Row.DataItem, "Status")
2. rowValue = rowValue.ToUpper
3. If InStr(rowValue, "REJECTED") Then
4. ' color the background of the row Ornage
5. e.Row.BackColor = Drawing.Color.Orange
6.
7. End If
8.
9. If InStr(rowValue, "ACCEPTED") Then
10. e.Row.BackColor = Drawing.Color.Green
11.
12. End If
13.
14.
9. Line Nos. 9 to 12 are newly added to our source code. Run the page in a browser to
see the changes. My GridView’s display is as below
