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
}
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.
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
i am using a usercontrol with repeater for custom paging in grdiview. Everything works fine. I am able to display link buttons and able to pull exact records. Now i have a little user friendly requirement. The pager usercontrol should appear at top of grid and bottom of grid. For that i have placed two instances of usercontrol. I am supposed to place same instance of usercontrol in two places so that whatever button click in any instance should happen in all available instances. The issue is i clicked page 2 (link button) in top pager user control. Its changed to selected mode(non clickable) where as bottom remains same, page 2 is clickable. How can i proceed?
I have a 3 text boxes. When i enter datas in and click the button it displays the gridview with filtered data. Now my problem is if there is no data in gridview it has to show "no data" so I used emptydatatext property.. The problem is, in the page load itself it shows "no data"
When I click on the Alphabets it will show the details of a player...however, when that particular letters has no details of the player..I want to show."No results can be found"..Is there anyway to do it?
I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
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.
I have a ShoppingCart UserControl on MasterPage. I have a following functionality: User adds item to the cart. after clicking the button "Complete Sale" in UserControl the page is redirected to "CustomerInfo.aspx" and after filling the Customer information and clicking on submit which is on CustomerInfo.aspx page i want to call the "Complete Sale" click event of UserControl from "Customerinfo.aspx" page.
How to display empty GridView to insert new record if no data retreived for some record on the result from data table?Actually i am trying to give a user an option to add recrod from Gridview.

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this title if the datafield is empty. Here is what I have done so far.
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?
I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)

I think I am not a beginner in asp.net, but now maybe I dont see the solution because it must be so easy..I have a simple Repeater on an UserControl(ascx).After a Postback on a button click I would like loop trough allthe Items from the Repeater, but the RepeaterItem-Collection is Empty!!!!!But NOW it comes, when I move the whole code from the UserControlto the Codebehind of an Page, and move the Repeater also to the Page.It works!!!! The Items-Collection are not empty after the Postback!!!Here is the simple Codebehind from the UserControl:
