Right now I have controls that are in my update panel and change the data in my gridview they work fine, but then i thought it would be cool to have the controls in the header of my gridview. But when i add them to my header and hit the button/run the function i get the failed to load viewstate error.[code]

My page has a drop down whose values are dynamically populated. Based on which item is selected, a number of TextBoxes are dynamically created during runtime.The user then fills in information into the textboxes and clicks a submit button.After postback from the submit button, I need to again dynamically create the TextBoxes during Page_Init (BEFORE LoadViewState) so that after the ViewState loads, my Button_Click event can save/do whatever with the user input. PROBLEM is, I cannot recreate the textboxes based on the selection in the dropdown, because the dropdown hasn't been "selected" yet by LoadViewState.SO, how can I read from the view state, create my textboxes, then let the viewstate populate the textboxes, and then the Button_Click will use the values??The one thing I've attempted is to override the LoadViewState function so that I can read from the view state, create the boxes, and then load the viewstate again. This did NOT work, because the debugger never seemed to hit my overridden function.[code]

Is there a way to place the insert row below the header in a gridview instead of in the footer?
how one might go about binding to a gridview in ASP.Net 4 in a scenario where the first row of my gridview should be the headers, the second should be a combobox for each column and the third is the beginning of my actual datasource.
If you can imagine what I am trying to achieve is an ability to create a binding between each column in the datagrid and another datasource. This binding is created by the user selecting a value in the comboboxes. However no matter what I try I cant seem to achieve this.
HeaderText1 | HeaderText2 | HeaderText3
ComboBox1 | ComboBox2 | ComboBox3
DataRow1 | DataRow1 | DataRow1
DataRow2 | DataRow2 | DataRow2
DataRow3 | DataRow3 | DataRow3
I am binding a data set to a GridView in VB .net. I have some custom sorting setup, and want to display an icon next to the header if one of my 3 options is selected.
I've read a lot of methods in doing this, and I see Gridviews even have a ASC and DESC header style I can associate with the view. I have 2 problems with this, though:I am sorting a List with linq on Sort Trigger, then binding it to the datagrid.
The reason I do it this way, is I want to maintain multiple sort levels, ordering by 3 columns rather than 1.
Edit for clarity Specifically what I want to do is loop through the value of a GridView's Header text, see if it matches what I have saved in viewstate, and if so add an image for that header in particular. Something essentially like below, however headerRow.Cells(y).Text is always returning "", even when the header has text:
Sub gvPatronData_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
Dim savedSortDirection(), savedSortColumn() As String
Dim headerRow As GridViewRow = gvPatronData.HeaderRow

Here is what I am doing. I create two buttons in a header row of a gridview that i created. The buttons are +page and -page. When -page is hit I remove the paging and all the data goes down the page and -page disappears and +page is there.
Here comes my issue When I hit +page I must be double postbacking because one row of my data disappears. I will provide the code below. What can i do to fix this??

So as you can see, when one or the other is hit I set a textbox to some value then i do a partial postback to my Gridview which is in that Updatepanel.
I need to create a gridview which fills its column with data from an excel sheet and for each column in the gridview, the header should contain a drop down list with listitems like telephone, name, price which the user will select and set as the header for the particular column. I imported data into gridview but I am not able to create a drop down list in the gridview. If I try to create a dropdownlist in the designer page, it is just creating the dropdownlist in the gridview header but not populating the data. So How can I create a dropdownlist in the header of the gridview while populating its column data from excel sheet.
The code I used to populate data into gridview is
Dim con As String = ""
Select Case Extension
Case ".xls"
'Excel 97-03

I want to set header column width for grid view. I tried HeaderStyle-Width="30px". But it is depending on Item columns. The column width is setting based on item value. But I want fixed width even if it has value or empty.
View 2 RepliesI realise there is a solution for this but I am struggling to get it to convert to VB correctly.I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.However due to the post back the grid will disappear until the second value is selected and looks awful.Is there anyway within VB to allow the header to stick around if there is no data within the grid view?

I am currently working with a gridviews in asp.net(vb). I have it where I am able to pass information from gridview1 to gridview2 on the next page. However, what I need to do now is pass a variable from a column in gridview2 to the header of that page. i.e. in Gridview2 we have a column and all results are the same, the column header is StoreName and all the data for column is Sears. I know how to make the entire column invisible, but at the top of the page I need a sentence that looks like this:
Store Information for Sears
I am having trouble with what the code would look like for that line, all the thing I have tried have resulting in using a variable before it is declared. I need this line to be dynamic as the results will not always be for Sears.
I'm currently counting all the checked checkboxes in an asp.net gridview using:
$('#cphMain_gdvSalesOrder').delegate('input:checkbox', 'click', function() {

Whereas I need to count all the checkboxes that are checked apart from the one in the header.

I have ASP gridview bound to an Entity Data source which works no problem, however when I try to programmatically change a header columns text, it appears to break the styling and will not allow sorting either, below is how I am trapping and changing the Header row column text.
Protected Sub gv1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv1.RowDataBound
If e.Row.RowType = DataControlRowType.Header Then
'retrieve the values from the userdeftable

I tried my best to shrink down the program to the following code. In this example, I have UK and USA as valid countries. If someone lives outside those countries, I wanna show an error message and highlight them on the gridview. For example, John and Chris are from China so they should be highlighted on the gridview. Either just Name or the whole row can be highlighted.

I upgraded a working VB.net windows application from VS2008 to VS2010 (a fairly simple form to process some data) and I get 15 warnings "Load of property 'X' failed" where 'X' refers to what looks like system variables like OutputType, StartObject, RootNamespace, AssemblyName, Option Explicit and so on. I also get two errors pointing to the Form1.Designer.vb file which I is the DesignerGenerated file saying that "My' is not a member of '<Default>'Originally I just used the upgrade wizard, resulting in these warnings. Next I tried creating a new project and adding the relevant files using the VS "Add Existing" function. I have also looked for answers in the forum and on-line but found none. This has got to be something simple I am overlooking.

The problem is with the bit in bold. The debugger says the following:
Error 1 Reference required to assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' containing the base class 'System.ComponentModel.Component'. Add one to your project.
I've checked and the system object exists but it is marked in the object browser with brackets as "Compact Framework". I have tried to remove this and replace it with one not labeled with "compact framework" and the error does go away but then the application doesn't run in the WM 6.5 classic emulator Producing a "failed to load all components.
