I have an ASP.NET Dynamic Data web application, with an entity called ActivationResource. One of the properties of this is a CellPhone field. Now, whenever I open a List or Details view of one of these entities, the cell phone number displays for a moment then disappears.
View 1 Replieshave an ASP.net 4.0 page containing a GridView, where during the Page_Init event I'm dynamically adding BoundField columns to the gridview. I also have some custom sorting and paging methods that I use with this gridview, which result in postbacks on the page. In Chrome, Firefox, Safari, and Opera the gridview behaves as expected. HOWEVER, in IE 6, 7, or 8 when I click to sort a column in the gridview, or go to the next page of results in the gridview, it does not bind on postback, returning nothing back to the browser. Again, in anything but Internet Explorer, paging and sorting (frankly any postback event) brings back the gridview in its expected state. I only have the problem in IE. Relevant snippets of my code follow, where you'll see my Page_Init event calling a method in my WebFunctions class to add the BoundField columns for the table I pass to it, and my Page_Load event that calls the method in the user control responsible for binding my dataset to the gridview. Initial page load works in all browsers, but postback loading of the gridview only works in non-IE browsers.

I populate two dropdownlist in asp.net. Both are assigned to a required field validator.
The codebehind is as below
if (!Page.IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("emp");
dt.Columns.Add("ename");
[Code]....
Now what happens is when I choose a field, and then once again go and choose"-- Select--", the validator appears and disappears.
Why doesnt the validator stay? Where am I going wrong?

I have a dropdown on page, a place holder and a save button on my form.Now, I am creating a textbox on selectedIndexChanged event of dropdown list and adding it to placeholder. And on button click I want to access the control, but on click event, I find the textbox as null. Here is my code

And button Save click event

I have created a Dynamic Data site against an Entity Framework Model
I have 2 fields which are nvarchar(max) in the DB and they do not get rendered on the list view
This is probably a sensible default
But how do I override this? Have tried adding various attributes to my MetaData class e.g
[ScaffoldColumn(true)]
[UIHint("RuleData")]
I want to create dynamic template field in gridview at code behind. Kindly let me know how to create this.
View 2 RepliesI have created a formview with 4 dynamic controls fields that LINQ to a database.

There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'totalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.
I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

View 1 RepliesHave spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension.Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated. The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values.Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :)Attribute I created:

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
you save data into a dynamic hidden field ,which is created dynamically during the handling of some postback event.what is the best way to retrieve it from this field upon a postback, (besides searching the request for the key of this hidden field and then retrieving the corresponding value as in the code below)?
protected void Button2_Click(object sender, EventArgs e)
{
bool found = false;
for (int i=0; i<this.Request.Form.Keys.Count; i++)

I have an input field on a webpage that contains a credit-card number. What is the best way of preventing the browser from caching this value?
Any solution needs to work on a large selection of browsers.
I am running into a weird issue. Please follow the comments in the attached code, along with the code.
Basically - I am trying to let a dynamic control class decide on what its javascripts are and what it wants to send to the browser.
But for some reason, this is not working - the javascript is not getting written to the browser page after the post back, even though I see the dynamic control on the browser page.
Here is the code snippet:

The week of torture and confusion at a higher level.I added a custom profile provider.
<profile defaultProvider="MySqlProfileProvider">
<providers>
<remove name="AspNetSqlProfileProvider"/>[code]...
I had to add the <remove name="MySqlProfileProvider"/>as it error with "the entry MySqlProfileProvider has already been made."The problem now is that it will only hold the data the first time I log in and create the account. Everything run find until you close the browser and try to log in the next time. Then the pages that use the profile properties tells me that there is no profile data for the same fields like there name for this user.It was there the first time and save it but the 2nd login it gone. Seems to me that the remove actually removes the data even when you save itI got it to work on the local server by setting MySqlProfileProvider up in using IIS managment tools. My local now rund fine. However my service provider will not make the manual entry for me.
I have a gridview where in the users are allowed to edit certain data and there is an update on top of the page which will send out all the changes made inside the GridView. But, the problem is , as soon as the update button is clicked, the grid disappearsand no update is made. This problem occurs when the size of the data on the page is huge. When we have less amount of data on the gridview, It does update. But, when there is a huge amount of data on the gridview, it does not. We have tried to increase the page size on the server, but to no use.
