How do i edit the column header of the GridView control on a web form? I have added a Table to DataSource as:
Me.gvSearchBrandList.DataSource = ds.Tables(0)
in here "gvSearchBrandList" GridView control But the GridView control display the column headers of the Table in the database. But how do i edit those column name in the GridView?
I have to create a report that lists tests that a student has taken and how they answered each question...the column header layout (roughly) looks like:
Test #1 1 2 3 4 5 Test #2 1 2 3 4 5
TestA A B C D E TestB C C B C E
The problem is that the Gridview doesn't seem to like repetitive column names and is renaming the second set of Question #s to something else.
I am struggling to show different views of gridview with database values. Here is my requirement. Database Table:I need to show one drop downlist with three values 1,2,3.

View 2 RepliesI have a gridview where I need to have column names within 1 sortable pageable gridview as the same name, but when I set up the sql query as
select x as 'col', y as 'col', z as 'col'
it shows up in the gridview with autogeneratecolumns on (theres a lot of columns in the page I don't feel like not autogenning it)
and it shows up as
col
col1
col2
in the gridview but I want it to just be col, col, and col. I understand that this could cause a sorting problem without turning autogenerate columns off, but I was hoping there was some type of work around.
VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.
I am using Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items

I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
I have a DataGridView which populates from an SQL query just fine in default mode
using these table names
[firstName] [varchar](20) NOT NULL,
[lastName] [varchar](20) NOT NULL,
[code]....
I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?
Is there any way to get common control names like Save, Copy or Undo Redo in the user's windows language? (I saw this in some programs which weren't made for my windows language. Also the Yes No Massage Boxes will change...)

I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
I have a gridview that contains value of every rows read from a text file. What I want to do is, edit and delete the selected row on the gridview. I already have the code to show every row on the textfile:
[code]...
What I am going to ask is, how do I get the index of selected row return and fill the value to the textbox then update it to the textfile?
I have a requirement to allow users to browse directories on our file server, and allow the users to navigate to an excel file open it, potentially update it and save it. I have it working. I have 2 gridviews - the first binds to an array of DirectoryInfo and the second binds to an array of FileInfo. I render the name of the file as a link in the grid, like this:
a href='file:///<%# Eval("FullName") %>' target="_blank" >'<%# Eval("Name") %>'
When the link is clicked, the excel file is opened within a browser. In order to save, it seems they have to do 'save as...' and it's confusing. Here is where my questions are. What's the difference between opening an excel file within a browser, vs. opening it with excel? Can I have a link to the file in my grid as above, but cause it to open using the Excel application instead of the browser? Does it matter that the excel files are on a file server? I think my users would be more comfortable editing the file within Excel - not in the browser. How can I accomplish this?
I have a gridview that appears in a modal popup that is generated dynamically and is bound to a dynamically generated SqlDataSource. I did this to hopefully take advantage of the gridview's automatic editing capabilities. My problem is that when the edit button is clicked the modalpopup closes due to a full postback in spite of the fact that my gridview is in an update panel. I looked at solutions here and here but neither fixed the problem. I've also tried every combination under the sun regarding the positioning of the ModalPopupExtender in relation to the update panel etc, and have tried changing UpdateMode to conditional as well.

<span class="none"><asp:Button ID="btnDummy" runat="server" Text="Dummy" /></span>

Im using Visual Studio 2008, i have a gridview which gets data from an SQL table. I have added the Edit option which is part of gridview.
The data has a primary key set.
How do i redirect to another URL when the edit option is clicked.
This action should also assign the primary key as a URL Parameter, causing only that specific record to show on the Edit page.
I have gone through this article: Button field in Gridview.
I would like to show different values in a dropdownlist, while editing a gridview, depending on which user is logged in. For example...
The officer would see "Approved by Officer" status.
The director would see "Approved by Director" status
I am trying to add these programatically to a dropdownlist which I have in the edit template of my gridview (approvalsGrid). Here is my code:
Protected Sub ApprovalsGrid_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles ApprovalsGrid.RowUpdating
Dim ApprovalEditDD As DropDownList = CType(ApprovalsGrid.Rows(ApprovalsGrid.EditIndex).FindControl("ApprovalEdit"), DropDownList)

I do not get any errors. But get an empty dropdown with no items. Am I using the correct event?
