I don't know. However if I wanted to know, I would read the MSDN documentation, starting here[^].

Hi,

i have two usercontrols say usrcntrl1.ascx and usrcntrl2.ascx. In usrcntrl2, i have just few links defined. And I want this usrcntrl2 to show up in every page just like header. And now i have usrcntrl1 to call usrcntrl2 on the page_load. How to use nested usercontrols in this case? Is it possible ?

Not sure if you have figured it out yet, but I think the problem is where you register your startup script.

It should point to the page (page where the control is loaded) and not to the control itself.

You can try : ScriptManager.RegisterStartupScript(this.Page,typeof(this.Page.getType()) ,"ScriptKey","alert('HI')", true);

Hope this helps.

Can not reference text value in footer of Gridview control [modified]

I have been struggling with this all week end ....
I am use Visual Web Developer 2010 Express.

I am trying to implement adding a new record using the Gridview footer.

I have an example that works fine that I got from http://www.aspdotnetcodes.com/GridView_Insert_Edit_Update_Delete.aspx.
My situation is a little different .. as I am using master page and the Gridview is in a page derived from the master page.

I have tried:

Dim txtNewName As TextBox = DirectCast(GridView1.FooterRow.FindControl("NewName"), TextBox)

"NewName" is the ID of one the textbox controls in the footer of the Gridview.

When I try referencing ... txtNewName.Text ... it returns a null value.

There must be some trick to referencing this .Text value when using the Gridview that is within a Content Place Holder that results when using a page that was created using a master page.

Thanks in advance for any possible help with this problem ...

I ma trying to determine if user is browsing my website from mobile device. I found the IsMobileDevice and tried to use it this way:

<pre>
if (Request.Browser.IsMobileDevice == true)
{
Response.Redirect("http://mobile.JassimRahma.com/");
}
</pre>

but whenI browsed from my Blackberry Curve 8520 it's going to the normail website (full) which means it didn't determine it's a mobile? why? and how can fix this?<pre></pre>

By default the aspx file take the browser as system in order to specify its a mobile we should install Aspnet_regbrowsers.exe from the below specified folder
Once you install
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regbrowsers.exe

or
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regbrowsers.exe

You will find the browser detection files in
C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers

text formatting control

Is there a text formatting built in control for ASP or is this something that has to be done manually? I am speaking like maybe something like what you see in this very forum.

Nothing bundled with Visual Studio, if thta's what you mean. But there are plenty of third-party offerings. Perhaps the best of the free / open-soource ones is TinyMCE[^]

You might have more luck Googling if you try searching for "HTML editor" rather than "text formatting".....

Hello,
I am following a sample project from this link: http://www.wewill.cn/n2020c22.aspx

in ConcatPerson impelementation, go to this part,please
public static int Save(ContactPerson myContactPerson)

then in that method they use foreach loop.

int contactPersonId = ContactPersonDB.Save(myContactPerson);
    foreach (Address myAddress in myContactPerson.Addresses)
    {
      myAddress.ContactPersonId = contactPersonId;
      AddressDB.Save(myAddress);
    }

I don't understand the above code?why he use loop?Could you please some one explain more.

thanks for helping me in this matter.

AFACT without reading the whole article, the Save operation returns the contactPerson object's ID [probably] generated by the SQL Server.
The loop sets the "backward" reference ID from the Address object to the "owning" ContactPerson object.

Sort of a cross between Lawrence of Arabia and Dilbert.[^]

Hi guys

I have a sample Code and misunderestanding with one parameter.however it may seems stpd question for you professional guys.

public DataObjectFieldAttribute(
	bool primaryKey,
	bool isIdentity)

<br />
primaryKey<br />
Type: System.Boolean<br />
true to indicate that the field is in the primary key of the data row; otherwise, false.<br />
isIdentity<br />
Type: System.Boolean<br />
true to indicate that the field is an identity field that uniquely identifies the data row; otherwise, false.<br />

the question is what is the meaning of isIdentity here?

Isn't that clear to you? In your data row, Is this field identity field? What is Identity Filed, see here[^]
