Binding data from one GridView to anther GridView after selecting some rows in the first GridView.
Binding data from one GridView to anther GridView after selecting some rows in the first GridView

Here is an example of binding data from one GridView to anther GridView after selecting some rows in the first GridView. First, we will create a GridView with a checkbox and two buttons in the footer: one for searching and another for adding data from one GridView to the other.


XML
<asp:GridView ID="grdDocChk" DataKeyNames="DOCCODE" 
        runat="server" BackColor="White" BorderColor="#CC9966"
        BorderStyle="None" BorderWidth="1px" 
        CellPadding="4" Style="z-index: 110; left: 208px; position: absolute; top: 416px" 
        Visible="TRUE" AutoGenerateColumns="False" ShowFooter="True" 
        AllowPaging="True" Height="10px">
     <FooterStyle BackColor="#FFFFCC" ForeColor="#330099" />
         <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" 
                 ForeColor="#663399" />
         <RowStyle BackColor="#EEEEEE" BorderColor="CornflowerBlue" 
                 ForeColor="Black" Height="30px" />
        <PagerStyle BackColor="DarkGray" />
        <HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
 <Columns >
   <asp:TemplateField >
     <ItemTemplate ><asp:CheckBox ID="chkBox" runat =" server" /> </ItemTemplate>
         <FooterTemplate >
        <asp:Label ID="lblDocCd" runat ="server" Text ="Doctor Code" />
        <asp:TextBox runat ="server" ID="txtDocCd" />
        <asp:Label ID="lblDocNam" Text ="DoctorName" runat ="server" />
        <asp:TextBox runat ="server" ID="txtDocnam" />
        <asp:Button ID ="cmdSearch" CommandName ="Search" 
            runat ="server" Text="Search" Width="60" />
        <asp:Button ID ="cmdAdd" CommandName ="Add" 
             runat ="server" Text="Add" Width ="60" />
        </FooterTemplate>
      </asp:TemplateField>
        <asp:BoundField HeaderText ="Doctor code" DataField ="DOCCODE" />
        <asp:BoundField HeaderText="Doctor name" DataField ="DOCNAME" />
               </Columns>
</asp:GridView>

Now create another GridView without checkbox but containing the same columns.


XML
<asp:GridView ID="grdDocTxt" DataKeyNames="DOCCODE" 
     runat="server" BackColor="White" BorderColor="#CC9966"
     BorderStyle="None" BorderWidth="1px" CellPadding="4" 
     Style="z-index: 111; left: 696px; position: absolute; top: 512px" 
     Visible="False" AutoGenerateColumns="False" AllowPaging="True">
    <FooterStyle BackColor="#FFFFCC" ForeColor="#330099" />
    <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" 
               ForeColor="#663399" />
    <RowStyle BackColor="#EEEEEE" BorderColor="CornflowerBlue" 
                ForeColor="Black" Height="30px" />
    <PagerStyle BackColor="DarkGray" />
    <HeaderStyle BackColor="#000084" 
           Font-Bold="True" ForeColor="White" />
    <Columns>
      <asp:BoundField headerText="doctor code" DataField ="DOCCODE" />
      <asp:BoundField  HeaderText="doctor name" DataField ="DOCNAME" />
      <asp:TemplateField  Headertext="DoctorRole">
	        <ItemTemplate >
	        <asp:DropDownList runat="server" ID="cmbDocRole" >
	        <asp:ListItem>Select</asp:ListItem>
	        <asp:ListItem>Surgeon</asp:ListItem>
	        <asp:ListItem>Asst.Surgeon</asp:ListItem>
	        <asp:ListItem>Anesthesia</asp:ListItem>
	        </asp:DropDownList>
	        </ItemTemplate>
	        </asp:TemplateField>
	        <asp:templatefield HeaderText ="Charges">
	        <ItemTemplate >
	        <asp:TextBox ID="txtChrgs" runat ="server" />
	        </ItemTemplate>
      </asp:templatefield>
    </Columns>
</asp:GridView>

In page load, bind data to the GridView grddocchk.


VB
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not IsPostBack() Then
    dim sqlstr as string
    sqlstr = "select DOCCODE,DOCNAME from TBL_ADM_MS_DOCTOR  where AND DOCACTIVE = 'A'"
    binddata(sqlstr)
End Sub

Here is the function for binding data:


VB
private sub bindData(sqlstr as string)
    SqlConnection sqlConnection = new SqlConnection ( "connectionString" );
    SqlDataAdapter sqlDataAdapter = new SqlDataAdapter ( sqlstr, sqlConnection );
    DataSet dataSet = new DataSet ();
    GridView1.DataSource = dataSet;
    GridView1.DataBind ();
end sub

After clicking the Search button in grddocchk, the GridView will be filled with the selection criteria, i.e., depending on the value in the textbox txtdoccode, txtdocname GridView should be filled. If we click the Add button, then rows which have been checked in grddocchk will be added to grddoctxt.


VB
Protected Sub gvDocChk_RowCommand(ByVal sender As Object, ByVal e As _
               System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvDocChk.RowCommand
    If e.CommandName = "Search" Then
        sqlstr = "select DOCCODE,DOCNAME from TBL_ADM_MS_DOCTOR  where DOCHSPCODE='" & _
                 gappln_data.appln_gHspCd & "' AND DOCACTIVE = 'A'"
        txtdoccd = CType(gvDocChk.FooterRow.FindControl("txtdoccd"), TextBox)
        txtdocnam = CType(gvDocChk.FooterRow.FindControl("txtdocnam"), TextBox)
        If txtdoccd.Text <> Nothing Then
            sqlstr = sqlstr & " AND DOCCODE like'" & Trim$(txtdoccd.Text) & "%'"
             bindData(sqlstr)
        End If
        If txtdocnam.Text <> Nothing Then
            sqlstr = sqlstr & "AND DOCNAME like'" & Trim$(txtdocnam.Text) & "%'"
            bindData(sqlstr)
        End If
        If gvDocChk.Rows.Count = 0 Then
            MsgBox("record not found", MsgBoxStyle.Information, "MasterHealth")
            txtdoccd.Text = ""
            txtdocnam.Text = ""
        End If
    End If
    If e.CommandName = "Add" Then
        Call add_gvdoc(gvDocChk, gvDocTxt)
        gvDocTxt.Visible = True
    End If
End Sub

Here is the function for adding a GridView to another:


VB
Protected Sub add_gvdoc(ByVal gvdocchk, ByVal gvdoctxt)
    dtable.Columns.Add(New DataColumn("DOCCODE"))
    dtable.Columns.Add(New DataColumn("DOCNAME"))
    For Each gvr As GridViewRow In gvdocchk.rows
        chek = CType(gvr.Cells(0).FindControl("ChkBox"), CheckBox)
        If chek.Checked = True Then
            drow = dtable.NewRow()
            drow("DOCCODE") = gvr.Cells(1).Text
            drow("DOCNAME") = gvr.Cells(2).Text
            dtable.Rows.Add(drow)
        End If
    Next
    gvdoctxt.datasource = dtable
    gvdoctxt.databind()
    gvdoctxt.visible = True
    gvdocchk.visible = False
End Sub
