SqlDataSource Control in ASP.Net

SqlDataSource is intended to replace the ADO.NET code you would normally write in a page to create a connection and command to query a database. Because the data queries are specified directly as properties of the data source control, this is sometimes called a two-tier model, because the data queries are still maintained in page code.

<asp:SqlDataSource ID="SqlDataSource1" runat="server"></asp:SqlDataSource>

BindData in GridView using SqlDataSource:

.aspx page

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1">

</asp:GridView>   

<asp:SqlDataSource ID="SqlDataSource1" runat="server" SelectCommand="insert_reg" ConnectionString="<%$ ConnectionStrings:mycon %>" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

Insert_reg is a StoredProcedure created in backend.which described below.In ConnectionString mycon is an object created in Web.config.

mycon is connection object created in web.config which is described below.

RowEditing event is used to enable editing in GridView

protected void GridView2_RowEditing(object sender, GridViewEditEventArgs e)

{

GridView2.EditIndex = e.NewEditIndex;

}

 

RowCancelingEdit event is used to cancel edit mode.

   

protected void GridView2_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

{

GridView2.EditIndex = -1;

Response.Redirect("Default3.aspx");

}

The zero-based index of the row to edit. EditIndex = -1, which indicates that no row is being edited.

Add , updateand Delete data in GridView using SqlDataSource

 

The RowCommand event is raised whenever any button associated with a row in the GridView is clicked. This provides for programmatically determining which specific command button is clicked and take appropriate action.

Here this event is used for Inserting data

protected void GridView2_RowCommand(object sender, GridViewCommandEventArgse)

{

      string strid = (TextBox) GridView2.FooterRow.FindControl("TextBox3")).Text;

 

string strpd = ((TextBox)GridView2.FooterRow.FindControl ("TextBox4")).Text;

 

string strname = ((TextBox)GridView2.FooterRow.FindControl ("TextBox5")).Text;

 

SqlDataSource2.InsertParameters["id"].DefaultValue = strid;

SqlDataSource2.InsertParameters["pass"].DefaultValue = strpd;

SqlDataSource2.InsertParameters["name"].DefaultValue = strname;

 

SqlDataSource2.Insert();       

}

Row updating event is used for updating data

protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

string strFirstName = ((TextBox) GridView2.Rows[e.RowIndex].FindControl("TextBox6")).Text;

 

string strLastName = ((TextBox) GridView2.Rows[e.RowIndex].FindControl("txtbx1")).Text;

 

string strDepartment = ((TextBox) GridView2.Rows[e.RowIndex].FindControl("TextBox2")).Text;

 

SqlDataSource2.UpdateParameters["id"].DefaultValue = strFirstName;

SqlDataSource2.UpdateParameters["pass"].DefaultValue = strLastName;

SqlDataSource2.UpdateParameters["name"].DefaultValue = strDepartment;

           

SqlDataSource2.Update();

}
