I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.
I have read serveral tutorials online and seem to be missing something. I am trying to have the leading 0's show up in columns by setting the format to text.
''' <summary> ''' This is required for the grid view to export properly ''' </summary>[code]......
In RowCreated of the GridView i add following script to select a row:
Select Case e.Row.RowType Case DataControlRowType.DataRow e.Row.Attributes("onclick") = Me.Page.ClientScript.GetPostBackClientHyperlink(Me.MainGrid, "Select$" & e.Row.RowIndex) End Select
This works like a charm(i thought).But when i debug the SelectedIndexChanging and the following SelectedIndexChanged events, i observe that the RowState of the selected Row switches from normal{0}/alternate{1} to 3 instead of selected{2}. This occurs between SelectedIndexChanging and SelectedIndexChanged. Why does this happen? The next time i programmatically set the selectedIndex(f.e. after a new row was created), i have two rows that are selected and no (un-hacky) way to deselect the old in RowDataBound, because of the invalid RowState of 3(should only be 0,1,2,4 or 8).
I have a button on the page and a gridview with checkboxes on the first column. The gridview is bound to a List. On buttonClick, I need to retrieve the underlying bound data item (MyEntity) for each selected row. How can I do this? I can't simply recreate MyEntity based on the gridview columns, because I am not displaying all the fields of MyEntity. I need a way to get a hold of MyEntity based on the key (MyEntityId).
I am able to export a gridview to excel, my problem is that I cannot figure out how to remove the formatting from coming over from the girdview. Here is the code I am using to export the gridview: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections. I was told this was not possible at this time. I have now decided to use the following code:

I would like to export a GridView to excel, which is easy enough. But above the grid, in Excel, I would like some other information for identification. Can I somehow export things other than gridviews while then putting in the gridview below?
Edit:For some reason when the GridView1 is visible and I try to export, the entire page exports and not just the gridview. Not sure why!

I am trying to export gridview (HTML Based) to a pdf in asp.net+vb.net (backend). When I click on the Export to PDF button the download window shows, but when you click on open Adobe reader will open but displays the message
" Adobe Reader Could not open 'test[1].pdf' because it is either not a supported file type or because the file has been damaged ( for example, it was sent as an email attachment and wasn't correctly decoded) ".
The coding for export to pdf is same for 5 different reports of which 4 are working fine, as well as export to Excel is also working fine for all 5 reports. Does it have any relation with the itextsharp dll version? (I am using itextsharp version 3.1.1.0)

These routines (vb.net) allow you to dump a gridview to CSV, even if there are templated controls in the cells. It works, but I'm not thrilled with it.
What improvements should I make and why?

I want to make a gridview with 4 columns. (Checkbox, Hyperlink name Title, Dynamic name Price, Dynamic named ASIN#)I want to be able to add new rows to the gridview from three different strings. I have a function that looks like this:Private Sub displayData(title As String, cost As String, asin As String)Is it possible to even add new data to the gridview with these strings.I've looked all around online and most things deal with databases. I'm also not 100% sure how to initialize at gridview.
I have a gridview that contains user info and one of the columns is a date when the user was added to the system. Is it possible to use the GridView.onRowCreated method to check if the user was added within a given time frame? If the user was added within that timeframe, then the row is added, if not, then that row is not added.
Note that I can't modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.
