I have a dropdown list control on an aspx page that I need to pass the value of to an ascx page that I reference by using get/set. My problem however is after after I "set" the value, it seems to reset itself back to zero when I try to access it again.
Here's my code. I'm using 2 pages (index.aspx & testgridcontrol.ascx:
index.aspx:
-----------------------------------------------------------------------------
protected void Page_Load(object sender, EventArgs e)
{
TestGridControl tgc = new TestGridControl();
tgc.physicianID = Convert.ToInt16(dropDownListControl.SelectedItem.Value);
}
Here's my testgridcontrol.ascx page:
public partial class TestGridControl : System.Web.UI.UserControl
{
private Int16 _physicianID;
protected override void OnLoad(EventArgs e)
{
Response.Write(physicianID);
}
public Int16 physicianID
{
get { return _physicianID; }
set { _physicianID = value; }
}
-----------------------------------------------------------------------------
When I "set" this value, it's value is 3 however when I get to the line that reads "Response.Write(physicianID);", the value of physicianID is reset to zero. Any idea what I'm doing wrong? Thanks.

I suspect you are bnding the data to the grid every time the page loads. This will reset the value to 0.

Hi Christian. Thanks for the response but I don't think that's quite it. When I step through my code line by line, the process goes as follows:
--------------------------------------------------------------------
Index.aspx > TestGridControl tgc = new TestGridControl();
Index.aspx > tgc.physicianID = Convert.ToInt16(dropPhysicians.SelectedItem.Value);
TestGridControl.ascx > public Int16 physicianID > set { _physicianID = value; }
Index.aspx > End of class
Masterpagefile.cs > (my code then hits my masterpage)
TestGridControl.ascx > protected override void OnLoad(EventArgs e) > Response.Write(physicianID);
TestGridControl.ascx > public Int16 physicianID > get { return _physicianID; }
-------------------------------------------------------------
By the time I re-enter testgridcontrol.ascx after my code takes a detour through my masterpage file, my _physicianID variable is already reset to zero.
I hope this helps shed some light on my issue.
Thanks again.

Hi Goalie35,
I have a naive question for you. I seek to learn too, on this topic. I noticed on the Page_Load of your example, you have instantiated a new TestGridControl object and assigned it a value. But was the new instance added to the page's control collection?
Remember, your work is not yours alone. Somewhere, there are some codes written by others amongst us that depends on your work. By failing to see that you are part of their ecosystem, you are bound to break their code.

Good question as he is creating a new instant of usercontrol and i think he would have added one more instant of usercontrol by registering that user control in aspx Expecting the result on added user control

Hello everyone,
Is it possible to make a user upload a Word file (.doc) to the server and make the server save this file as an HTML file ?
Also after the conversion while an HTML file is created also there must be a directory created at the same place with the HTML file which have files related to the newly created HTML file.
Best Regards & Thanks

I think there are some third party tools by using them you can achieve this
Also if you have to display this document as an html then don't convert it just read the content and display it on aspx page
Thanks and Regards

Just a guess but it sounds like you may be missing the user control assembly on the live server? Maybe try searcing for that dll on the live box and see if it is there. If it is then, post some code so we can have a look.

I have a drop down list in my asp page. when I selectg an irem and click on a button it appears in the Grid view. But when I again come to the same page and click on the same item from Drop down list it and click on button it again add the same item onin the Grid view. So I need some validatiobn that if this item appears in Grid view Don't add in the Grid view. I can use customValidation control. But I don't know how to use it.
