I have a dataTable loaded with data, and set as a datasource for a gridview control.

When I click on any of the row on that gridview, I need to get that row only.

How is that possible?

Yes that is quite easily possible.

By clicking a row in a <code>gridview I suppose that you will have some unique key from that row. Once you have one or multiple value that can identify that row uniquely you can apply Select Filter to datatable to fetch whole row from datatable. It will return you collection of DataRow. Like

VB

Dim dataRows() As DataRow = dtChattable.Select(String.Format("Column1 LIKE '{0}%' AND Column3 = '{1}'", _
TextBox1.Text, TextBox2.Text))

If not a primary key but atleast it should have multiple value from that row that can find row uniquely.

Add a 'Select' CommandField Column to your GridView.

XML

<asp:CommandField HeaderText="Select" ShowSelectButton="True" />

Now when user selects a particular row, Row_Command event of the GridView is fired. So you do something like this

VB

Protected Sub GridView1_RowCommand(sender As Object, e As GridViewCommandEventArgs)
    If e.CommandName = "Select" Then
        'get the row index
            
        Dim rowIndex As Integer = Convert.ToInt32(e.CommandArgument) - 1 'in case there is no paging.
        'Now get the value from GridView against this row.
        'perform required operation
    End If
End Sub

By the way, you could have also tried Googling for a solution: select a row in gridview[^]

Hope this helps! :thumbsup:

Solution 4

Do want to display the select row to form or what.
For example if the first column of the grid in the unique key then use this

CStr(datagridview1.Item(0, datagridview1.CurrentCell.RowIndex).Value())

this will get the value of the first column of the select row

am hoping ur using vb.net
