Hi,
I'm using a simple Infragistic web combo in ASP .net with code behind in VB .Net 2003. It's a very basic combo box that is working fine with code behind in C# .Net  but the same code (logic) is not working in VB .Net. The problem I'm facing is that when I click on button1 and in it's event I simply write:
WebCombo2.SelectedRow.Cells(0).Value.ToString()
and it returns with a null object reference exception. When I debugged, I found the SelectedRow object null.
I'm using:
-> Infragistics NetAdvantage 2006 Volume 2 CLR 1.x
-> VS 2003 ASP .Net, code behind in VB .Net
here is the code:
<igcmbo:webcombo id="WebCombo2" runat="server" Height="20px"
DataValueField="User_Id" DataTextField="Logon_Name" Width="200px" Font-Names="Verdana" DataMember="User" Font-Size="8pt" BorderStyle="Solid" BorderWidth="1px" SelBackColor="LightSteelBlue" BackColor="White" ForeColor="Black" SelForeColor="51, 51, 51" Version="2.00" BorderColor="Gainsboro">
<Columns>
<igtbl:UltraGridColumn
HeaderText="User Id" Key="User_Id" IsBound="True" BaseColumnName="User_Id">
<Footer

<Header Key="User_Id"

</igtbl:UltraGridColumn>
<igtbl:UltraGridColumn

Hi all;
I want to be able to get the total number of rows in a gridview with out any sql code.
How would I do that?
Thanks
Hadi

U may use DataBound event of GridView, and use the Property
Gridview1.Rows.Count
Hope it helps u..
Regards,
Jay

Thanks for the reply, but this is not what I wanted. what you suggested only returns the number of rows per page. not all the rows of a gridview which is bounded.
I found the answer. You have to use the Selected event of the DataSource which you have bounded to the gridview.
e.AffectedRows
Thanks again

comm.CommandText = "select BrandID, Brand, ('Logo_Pics/'+BrandLogo) as BrandLogoFile from Brand";
SqlDataReader dr2 = comm.ExecuteReader();
DropDownList1.DataSource = dr2;
DropDownList1.DataBind();
dr2.Close();
this code above is to bind the sql database data to my dropdownbox1
i need help to make the first choice of the drop down list box to all
without putting in inside the sql database
can this be done?
example:
old:
1 // from sql
2 // from sql
3 // from sql
wat i want:
All // not from sql
1 // from sql
2 // from sql
3 // from sql

Hi,
First of all fill the drop down combo with the sql output. Then insert new item like this -
DropDownList1.Items.Insert(0, "All");

Don't write whole sentences in bold. It serves no purpose other than making it harder to read.
What you are using is not Java at all, it's Javascript.
DineshSharma wrote: this.Attributes.Add("onload", "setObj('Dinesh','Sharma',550,30)"); not working
Standard question #1:
What do you mean by "not working"?
The Page object (that "this" references to) is the page itself, not a control on the page, so you can't add attributes to it. So I assume that the error message is that the object doesn't have any "Attributes" property.
Put an id on the body tag and make it a server tag, so that you can access it from code behind:
<body id="Body" runat="server">
Now you can declare the reference and put the call to the Javascript in the onload event:
protected HtmlGenericControl Body;<br />
<br />
Body.Attributes.Add("onload", "setObj('Dinesh','Sharma',550,30)");

Until now I'm setting the Control page like this:
<%@ Register TagPrefix="Menu" TagName="Bottom" Src="Bottom.ascx" %>
On the top of the page.
But now I need to set the Src dynamicly.
eg.: <%@ Register TagPrefix="Menu" TagName="Bottom" Src="Session["ID"] + "/Bottom.ascx" %>
Something like this.
Now I know that this is not how to do it, but maybe you can help me?

Hi,
I am using asp.net 2.0. In this,i am using Cross Page Posting. From the second page, i am trying to reference a control (Label) in the prevoius page using 'PreviousPage' property.
Here, in the first page, that Label control is placed within the <asp:Content> tag. (ie I am using MasterPage's ContentPlaceHolder).
Page.PreviousPage.FindControl("lebelid") method return null.
I am tried with refering the NamingContainer before refering the actual control (Label), which is placed within that NamingContainer. It also gives me the output null.
In my previous page, the Label control present within the tag,
<asp:Content ID="Content5" ContentPlaceHolderID="BodyContent" Runat="Server">
</asp:content>
In my second page (using same masterpage) code behind file, i am refering like this,( in Page_Load event)
ContentPlaceHolder myContent = (ContentPlaceHolder)Page.PreviousPage.FindControl("BodyContent");
Still it returns null.
Can anyone help me in this? Thanks in advance.
Regards,
Jay

The sample code is updated slightly:
ContentPlaceHolder holder = (ContentPlaceHolder)Page.PreviousPage<code>.Controls[0]</code>.FindControl("BodyContent");

Dear member,
Thanks for your help. It works fine. But i dont know, what this Controls[0] represents?? Can u pls explain me.
Thanks a lot.
Regards,
Jay

It represents the MasterPage at runtime which in nature is the user control. If you set the Trace="true" in the first page, the control hierarchy of the trace info will give you some ideas.

 Once again Thank you very much .. I have understood.
