Asp.net - Gridview Binding With Combobox's In Header
Jul 27, 2010
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??
[Code]...
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.

I 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() {
var count = $('#cphMain_gdvSalesOrder').find('input:checkbox:checked').length;
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
e.Row.Cells(6).Text = App.Session.Company.UserDef3
End If
End Sub

I am trying to bind XML data into a gridview, after clicking the 'ButtonSaveToDataBase' button, the method will begin to read data from my gridview and load it into an array of my serializable class type and after that serialize it and finally store it into a XML type field in my SQL. The problem is When I call BindData() at the end of the serialization, it reads the XML from my database and successfully binded it but my gridview displays an empty row below my datas like this:

I'm still trying to understand and use Use Cases and Test Driven Development, but having a hard time crossing the line. I'm hoping someone can provide a good example of how setting a datasource and/or databinding a gridview could be accomplished using Test Driven Development. Here is my pseudo approach at it.

I am trying to add 2 databindings to a combobox. 1 will bind to the text, andthe other one will bind to the selectedvalue. However, I am only able to add one databinding to the combobox.
cmdCustomerID.DataBindings.Add(
"Text", TblCustomerBindingSource, "strCustomerID", True)
cmbCustomerID.DataBindings.Add(
"SelectedValue", TblCustomerBindingSource, "idxCustomer", True)
This is what I have done. Only the selectedValue DataBindings.Add is being captured.

I'm trying to bind data to a combo box but it does not appear to be working. I've setup the DataSet and the DataSetBindingSource and all this appears to be working, within the form design I can expand the little arrow in the ComboBox control and preview the data. This appears to be working but when the application is run, nothing appears in the drop down box.

I have set up at DataGridView "cdgvExp" for data entry. cdgvExp.Datasource = ExpTab. The datagridview can accept new rows according to how many entries there are. I will then use the data in ExpTab. The Fourth colum is called "Lot" and is a combobox in the datagridview. The goal is to have the Combobox in the fourth column have the datasource be LotTab which is populated according to other choices in the form. I am hunting for something that would work like an independant combobox like cbLots.datasource = LotsTab
How do I dynamically set the Datasource and Datamember of a combobox that is already set up in a datagridview?
