Move Selected Gridview Rows to Another Gridview in Asp.net

May 8, 2013
Introduction:

Here I will explain how to move or transfer selected checkbox gridview rows to another gridview in asp.net using c#, vb.net or copy one gridview row to another gridview in asp.net using c#, vb.net.

Description:

In previous posts I explained Display images in gridview from database in asp.net, Enable/Disable checkbox in gridview based on condition,
asp.net gridview examples and bind data to textbox control in gridviewBind data to dropdownlist  in gridview and many articles relating to asp.net, c#, vb.net, c#, vb.net. Now I will explain how to move selected rows from one gridview to another gridview in asp.net using c#, vb.net.

To implement this first we need to write the code in aspx page like this 


<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Tranfer selected gridview rows to another gridview in Asp.net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<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>
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
<br />
<b>Second Gridview Data</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>
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
</div>
</form>
</body>
</html>
Now add following namespaces in codebehind

C# Code


using System;
using System.Data;
using System.Web.UI.WebControls;
After that add following code in code behind


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));
DataRow dtrow = dt.NewRow();    // Create New Row
dtrow["UserId"] = 1;            //Bind Data to Columns
dtrow["UserName"] = "SureshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Chennai";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow();               // Create New Row
dtrow["UserId"] = 2;               //Bind Data to Columns
dtrow["UserName"] = "MadhavSai";
dtrow["Education"] = "MBA";
dtrow["Location"] = "Nagpur";
dt.Rows.Add(dtrow);
dtrow = dt.NewRow();              // Create New Row
dtrow["UserId"] = 3;              //Bind Data to Columns
dtrow["UserName"] = "MaheshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Nuzividu";
dt.Rows.Add(dtrow);
gvDetails.DataSource = dt;
gvDetails.DataBind();
}
protected void chkSelect_CheckChanged(object sender, EventArgs e)
{
GetSelectedRows();
BindSecondGrid();
}
protected void BindSecondGrid()
{
DataTable dt = (DataTable)ViewState["GetRecords"];
gvTranferRows.DataSource = dt;
gvTranferRows.DataBind();
}
private void GetSelectedRows()
{
DataTable dt;
if (ViewState["GetRecords"] != null)
dt = (DataTable)ViewState["GetRecords"];
else
dt = CreateTable();
for (int i = 0; i < gvDetails.Rows.Count; i++)
{
CheckBox chk = (CheckBox)gvDetails.Rows[i].Cells[0].FindControl("chkSelect");
if (chk.Checked)
{
dt = AddGridRow(gvDetails.Rows[i], dt);
}
else
{
dt = RemoveRow(gvDetails.Rows[i], dt);
}
}
ViewState["GetRecords"] = dt;
}
private DataTable CreateTable()
{
DataTable dt = new DataTable();
dt.Columns.Add("UserId");
dt.Columns.Add("UserName");
dt.Columns.Add("Education");
dt.Columns.Add("Location");
dt.AcceptChanges();
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;
dt.AcceptChanges();
}
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;
}

I don't think so your code will show the output you are showing in the Demo.gif

protected void gvUserInfo_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
con.Open();
GridView gv = (GridView)e.Row.FindControl("gvChildGrid");
int CountryId = Convert.ToInt32(e.Row.Cells[1].Text);
SqlCommand cmd = new SqlCommand("select * from State where CountryID=" + CountryId, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
gv.DataSource = ds;
gv.DataBind();
}
}
