Here i have explained how to Tranfer selected Gridview row Data to another gridview in Asp.Net C#.
Step 1) Add HTML:
<asp:GridView ID="gvDetails" AutoGenerateColumns="false" CellPadding="5" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server" AutoPostBack="true" OnCheckedChanged="chkSelect_CheckChanged" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="UserId" DataField="UserId" />
<asp:BoundField HeaderText="UserName" DataField="UserName" />
<asp:BoundField HeaderText="Education" DataField="Education" />
<asp:BoundField HeaderText="Location" DataField="Location" />
</Columns>
</asp:GridView>
<br />
<b>Second Gridview </b>
<asp:GridView ID="gvTranferRows" AutoGenerateColumns="false" CellPadding="5" runat="server" EmptyDataText="No Records Found">
<Columns>
<asp:BoundField HeaderText="UserId" DataField="UserId" />
<asp:BoundField HeaderText="UserName" DataField="UserName" />
<asp:BoundField HeaderText="Education" DataField="Education" />
<asp:BoundField HeaderText="Location" DataField="Location" />
</Columns>
</asp:GridView>
Step 2) Import Namespaces

Step 3) C#
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
BindSecondGrid();
}
}
protected void BindGridview()
{
DataTable dt = new DataTable();
dt.Columns.Add("UserId", typeof(Int32));
dt.Columns.Add("UserName", typeof(string));
dt.Columns.Add("Education", typeof(string));
dt.Columns.Add("Location", typeof(string));
// Create New Row and bind Data to Columns
DataRow dtrow = dt.NewRow();
dtrow["UserId"] = 1;

}

{

BindSecondGrid();
}

{

gvTranferRows.DataBind();
}
private void GetSelectedRows()
{

if (ViewState["GetRecords"] != null)

else

for (int i = 0; i < gvDetails.Rows.Count; i++)
{

if (chk.Checked)
{

}
else

}
}
ViewState["GetRecords"] = dt;
}
private DataTable CreateTable()
{

dt.Columns.Add("UserId");

return dt;
}
private DataTable AddGridRow(GridViewRow gvRow, DataTable dt)
{
DataRow[] dr = dt.Select("UserId = '" + gvRow.Cells[1].Text + "'");
if (dr.Length <= 0)
{
dt.Rows.Add();
int rowscount = dt.Rows.Count - 1;
dt.Rows[rowscount]["UserId"] = gvRow.Cells[1].Text;
dt.Rows[rowscount]["UserName"] = gvRow.Cells[2].Text;
dt.Rows[rowscount]["Education"] = gvRow.Cells[3].Text;
dt.Rows[rowscount]["Location"] = gvRow.Cells[4].Text;

}
return dt;
}
private DataTable RemoveRow(GridViewRow gvRow, DataTable dt)
{
DataRow[] dr = dt.Select("UserId = '" + gvRow.Cells[1].Text + "'");
if (dr.Length > 0)
{
dt.Rows.Remove(dr[0]);
dt.AcceptChanges();
}
return dt;
}
