Hi all,
I use gridview to display the data in Item table.
The edit and delete button works fine in the gridview initially.
When I search for particular records and display in the grid the edit and delete button does not work.
<asp:GridView ID="GridView1"
runat="server"
AutoGenerateColumns="False"
DataSourceID="SqlDataSource2"
AutoGenerateDeleteButton="True"
AutoGenerateEditButton="True"
DataKeyNames="iid"
>
<Columns>
<asp:BoundField DataField="iid" HeaderText="I.D" ReadOnly="True" SortExpression="iid"/>
<asp:BoundField DataField="iname" HeaderText="Name"/>
<asp:BoundField DataField="iprice" HeaderText="ItemPrice"/>
<asp:BoundField DataField="qtty" HeaderText="Quantity"/>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [item]"
DeleteCommand="Delete from item where iid=@iid;"
UpdateCommand="Update item set iname=@inameiprice=@ipriceqtty=@qtty where iid=@iid;"></asp:SqlDataSource>and the vb code is:
Dim con As New SqlClient.SqlConnection
con.ConnectionString = "..."
con.Open()
Dim cd As New SqlClient.SqlCommand
Dim r As SqlClient.SqlDataReader
cd.Connection = con
If choice.Text = "ItemID" Then
cd = New SqlClient.SqlCommand("select * from item where iid='" & val.Text & "'", con)
r = cd.ExecuteReader
GridView1.DataSourceID = String.Empty
GridView1.DataSource = r
GridView1.DataBind()
ElseIf choice.Text = "ItemName" Then
cd = New SqlClient.SqlCommand("select * from item where iname='" & val.Text & "'", con)
r = cd.ExecuteReader
GridView1.DataSourceID = String.Empty
GridView1.DataSource = r
GridView1.DataBind()
ElseIf choice.Text = "Price" Then
cd = New SqlClient.SqlCommand("select * from item where iprice='" & val.Text & "'", con)
r = cd.ExecuteReader
GridView1.DataSourceID = String.Empty
GridView1.DataSource = r
GridView1.DataBind()
ElseIf choice.Text = "qtty" Then
cd = New SqlClient.SqlCommand("select * from item where qtty='" & val.Text & "'", con)
r = cd.ExecuteReader
GridView1.DataSourceID = String.Empty
GridView1.DataSource = r
GridView1.DataBind()
End IfHow to add specific update and delete commands for each choice.
