InsertCommand (sql insert) using SqlDataSource / GridView

September 30, 2009


We need a set of controls (textbox, dropDowns, etc), then, when the user fill that, he/she clicks the “Ok button”, and the insert is performed against the database, and we want to use the “insert command” contained into the sqldatasource that is already being used by the gridview control. 

We usually think we need to use the Gridview to accomplish this task, but it’s not necessary at all.

If we have a sqldatasource like this:

   1: <asp:SqlDataSource ID="SqlDataSource2" Runat="server" 

   2: SelectCommand="SELECT * from TEST"

   3: ConnectionString="<%$ ConnectionStrings:AppConnectionString1 %>"

   4: InsertCommand="INSERT INTO TEST (testData) values (@testData)">

   5:     <InsertParameters>

   6:          <asp:Parameter Type="String" Name="testData"></asp:Parameter>

   7:      </InsertParameters>

   8: </asp:SqlDataSource>

The fill-in controls can be located outside the gridview, in any place in the page.

   1: <asp:TextBox ID="txtTest"  Runat="server"></asp:TextBox>

Also, create a button, give it an identity, and handle the click event as usual. After we click this button, we will perform the INSERT operation.

   1: <asp:Button ID="buttonOk" Runat="server" Text="Ok" OnClick="Button1_Click" />

In the code behind, assuming the sqldatasource object you want to use is called SqlDataSource1 :

   1: void Button1_Click(object sender, EventArgs e)

   2:   {     

   3:       SqlDataSource1.InsertParameters["testData"].DefaultValue = txtData.Text;

   4:       SqlDataSource1.Insert(); //CALL the INSERT METHOD

   5:   }

You can also add any data validation routine at this point.

Note that we called the insert method by hand after we set the values in the parameters as we needed.


Change Thickbox Title in runtime

June 8, 2009

The Quest.

You want to change the thickbox title, runtime or thought the ASP vb/c# code.


The thickbox title is stored inside a div ID TB_ajaxWindowTitle


Simply use Jquery to get your way to this DIV and change the value to the one you want:

   1: $("#TB_ajaxWindowTitle").val("New Title")

I request you to use jquery, because if you’re using thickbox, this means you already have jquery included in your page.

But if you do not want to use jquery, do this:

   1: window.document.getElementById("TB_ajaxWindowTitle").innerHTML = "New Title"

Doing that in Runtime with ASP.NET

Ok, first ask yourself “why” would you do that?. I Recommend you always (when possible) keep all your client code in the cient side, but if you have found a good reason, then, simply call the RegisterClientScriptBlock.

   1: ClientScript.RegisterClientScriptBlock(Me.GetType(), "scriptKey", "$("#TB_ajaxWindowTitle").val("New Title")", True)

This will work if you are in a ASPX page (inheriting directly or indirectly from System.Web.UI.Page).

If you are inside a component, call Me.ClientScript.Page.RegisterClientScriptBlock.

And yes, use Me.Page.getType() to fill the first parameter.
