Forms Data Controls :: GridViewHelper - Gridview Rows Mess Up
Jul 20, 2010
I have a gridview which is placed inside an updatepanel and a button outside the panel. And each gridview rows contains a radio button with 2 options. When i clicks on the button, an asynchornos post back occurs and I am vlidating the radio button values inside serverside button_click method, and shows an alert if any of the radio button is not checked. Everything is working fine till this point. Then i have introduced a GridViewHelper class[URL]for grouping the categories and displaying it as a group header. This also working fine when the page is loaded for the first time. For creating the group header, below code is placed inside the Page_Load event as mentioned in the link above:
Dim gvhelper As GridViewHelper
gvhelper = New GridViewHelper(Me.GridView1,
False, SortDirection.Ascending)
gvhelper.RegisterGroup("surveyqngroup",
True,
True)
'where "surveyqngroup" is the field name used for grouping
The real problem occurs when i click on the button. Asynchronospostback occurs, serverside method is called, after validating it shows the alert also. But the gridview rows mess up. An extra radiobutton appears in the group header row. Also few rows are missing from the gridview.

I am using the GridViewHelper [URL]to display gridview with group and subtotals. This seems to only work on BoundField and I am wondering how to get this work with TemplateField.
Dim helper As New GridViewHelper(Me.GridView1)
helper.RegisterGroup("DeptDesc", True, True) - Works
helper.RegisterSummary("Reg", SummaryOperation.Sum, "DeptDesc") - Throws Error Below
helper.ApplyGroupSort()
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Reg'.
<asp:BoundField DataField="DeptDesc" HeaderText="DeptDesc" SortExpression="DeptDesc" />
<asp:TemplateField HeaderText="Reg" SortExpression="Reg">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# IsSplit(Eval("EmployeeID")) %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

I am using a Gridview on a webform. Got the editing/updating all working correctly. Problem is, all the data is on one row and it is alot of data. I thought about splitting the data into 2 gridviews but then all of the employee data isn't lumped together like the higher ups want.
I have done research on a DataRepeater as it will give me the formatting I need it but it doesnt support editing.

I have a Gridview which is populated with data based on the selection of dropdowns in a web form. Once the gridview is displayed on the page the user has a "Print" button that will print the gridview. I need to allow the user to remove rows from the gridview prior to printing. I do not want to remove the data from the database, only from the displayed gridview.
I've added a column to the Gridview that has a checkbox which appears next to each row. The header of this column reads "Exlude". If the user checks a box next to a row then this row should be excluded from the printed gridview.Totally new to gridview .. don't know where to go from here.

I have developed a gridview that groups rows together based upon a field in the gridview. To separate each group, I have inserted a row that contains the name of the group.
However, I have hit a problem, what I need to do is to have an image button on the row I have inserted between the groups, which when clicked will hide and show the rows in that group in a toggle fashion. I can get the start of the row for a group, but I am unable to work the number of rows in a group and to then show and hide the rows in that group.

I'm developing an ASP webshop website (in VB). I've attached an sql database and put a gridview on the form which pulls up the product details from the database. I can turn on Edit and Delete in the gridview so it is easy to modify the products but how can I add new rows?
