Forms Data Controls :: FormView Disappears In IE8?
Aug 9, 2010
I am running Visual Studio 2008 Version 9.0.30720.1. I created a Web App with a FromView and in IE7 it works great. My company pushed an upgrade to IE8 and all of a sudden when I run my Web App to test it, the formview completely dissapears. I tried running IE8 in Compalability View but it still does not work.

I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

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.

I use Server.Transfer("pagename", True) to navigate from a page where two dates have been selected to a page with a gridview that uses the dates to query the database and display the results. The gridview initially displays correctly but when I operate the select or sort it disappears.

I've got a Gridview in which I use the RowDataBound handler to color the lines according to certain conditions
(ie if column x is value y then change the background-color of the row to z etc).
One problem though, as soon as I do a postback the coloring disappears altogether and all rows become white.
Is there some way around this so I can retain my background colors even after a postback?

I have a Gridview control with a panel inside a template column and I dynamically add a checkbox control through code to the panel and the checkbox has autopost set. My problem is when I click the checkbox it dissappears on autopost back. I have tried to recreate the control again on the event OnDataBound but when I cast the sender as checkbox I get nothing. How can I not loose my checkbox on postback and why is (Checkbox)sender return nothing.

I am populating a column in a gridview with a dropdownlist as follows:
[Code]....
[Code]....
When I edit the gridrow, the dropdown is there and I can select a new item.
But I can't find the dropdown during the rowupdated event. The cell control says it's a Textbox. All of the other items in the row are fine and I can get the data back. But I can't get the DropDown item.
Here are some of the things I have tried in the RowUpdating event:
DropDownList test = (DropDownList)e.FindControl("ddlPeriod");
//null
DropDownList ddl = (DropDownList)GridView1.Rows[e.RowIndex].FindControl("ddlPeriod");
//Also null
var test = row.Cells[8].Controls[0];
//Says its a textbox.

I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.

I have a datarepeater inside which I load a gridview. After the grid's binding is done I create an extra header line to group the columns (that's the only way I could do it, I couldn't figure a way to add an event for a control inside the repeater).That works fine and the page displays perfectly.However everytime I do a postback from other controls, I lose the 2nd header and 1 extra empty line appears at the top of the gridview

have 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 have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.
When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.
I don't understand why the GridView is disappearing when I click a column header.
Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?

I looked for examples for a news ticker and modified one I found to fit my needs. I created a web user control and everything works fine, even with a timer that ticks and refreshes the whole page, but not when I wrap just the user control in an update panel that is controlled by the timer. It works on page load, but then the data disappears on a timer tick. The code behind seems to be running fine and the variables have data etc., so I think it's the javascript, but I'm not sure where to go from here. C# code behind
