Hello Experts,

I think this is an easy one.  I need to set a variable to an object already my aspx.  Here's my code it's called during the page_load event.

        private void LoadSearchComboBoxs(string ComboName)
        {
            ComboBox TheComboBox;
            TheComboBox = Page.Controls[ComboName];
}

Open in new window


Thanks

Since you declared the reference TheComboBox to be of type ComboBox, you need to cast the thing returned by the indexing of the Controls collection (which returns "things" as type Control). In other words:

TheComboBox = (ComboBox)Page.Controls[ComboName];

Kaufmed - Thanks for your input.  I'm using:

            ComboBox TheComboBox;
            TheComboBox = (ComboBox)Page.Controls[ComboName];

But I'm getting the following errors

The best overloaded method match for 'System.Web.UI.ControlCollection.this[int]' has some invalid arguments      
Argument '1': cannot convert from 'string' to 'int'      

Is there a better way of doing declaring my object variable?

Hi,

Try this,

ComboBox TheComboBox;
TheComboBox =  (ComboBox)Page.FindControl(ComboName);

I'm trying to use TheComboBox = (ComboBox)Page.FindControl(ComboName);

but it's also not working might be because I'm using a content page.

Got it:

TheComboBox = (ComboBox)this.Master.FindControl("ContentPlaceHolder1").FindControl(ComboName);
