Web Forms :: Access Usercontrol's Hiddenfield From Content Page Code Behind?

Apr 21, 2010

I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.

I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.

alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.

I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.

objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value

why is the value null on the content page?

Forms Data Controls :: UserControl In Page / Hiddenfield In Each Is Not Empty?

Nov 2, 2010

I have a repeater which always has 1 UserControl, however the UserControl can vary, lets say it could be UC1, UC2 or UC3.

When I come to validate that a hiddenfield in each is not empty, I iterate through the repeater items but I have to do a findcontrol on UC1 check an exposed value, then do the same for UC2 then UC3. In all its a bit unwieldly.

What it would be great to do is iterate through the repeater items find the hiddenfield (which is the same name for each UC) and test that in one go, like below:

foreach(RepeaterItem item in Repeater1)

{
... some code here to start off with

HiddenField hfAnswer = (HiddenField)item.FindControl("HF_Answer");
if(hfAnswer != string.Empty)
do something here
}

Web Forms :: HiddenField To Post To External Website And Submit Data To Sql Database With Masterpage

May 12, 2010

I need to send some parameters to an external website using the <asp:HiddenField /> controls and also at the same time, submit data to a sql server database. The part for submitting the data to the database is working, but I need to try to get the parameters from the hiddenfields to also be passed through. I thought all I had to do is create the hidden fields and in the code behind, set the values from the textboxes that the user would fill out.

My source code is below:

[code]...

What am I missing? The hidden fields are losing their value before posting to the external website. I've looked everywhere to see why this won't work.

Use Different Name In Asp : Hiddenfield?

Jan 7, 2011

I have a for which is built within an ASP.net usercontrol. This form is then used within a CMS as part of integration with a merchant gateway. The gateway requires that a number of hiddenfields be passed in which is fine in the main however one of these needs to be called Profile. The CMS I am using also defines a global variable called Profile and as such when I try and add a hidden field with this ID I get errors.

Is there a way of setting the 'name' property to Profile, and the ID to something different?

JQuery :: Get The GridView HiddenField Value?

Dec 28, 2010

I'm making a GridView with like 12 fields and about 8 of them are hidden. I want to display those 8 as details of each row when I select the row with a button.
