Referencing Contents Of Gridview Cell?
Jan 9, 2010
I' working on an Office Supplies website for a college course I'm doing. I have most of the website created, I'm just working on the shopping cart element of it now.When the user goes to check out, I have a Gridview displaying the items the user wishes to buy as follows, it contains 3 columns, REF NBR, Product Name and Quantity, when the user clicks on the 'BUY NOW' button I want to take all the reference numbers from the Gridview and search teh database and deduct the Quantity from the number of items in stock.

I have a GridView and, using a fairly common method, I'm using a FooterRow and TemplateFields to provide the missing insert ability. So far so good.The footer contains a TemplateField with a LinkButton to provide the postback that does the insertion. In the handler for the LinkButton's click, the Insert() method is called on the ObjectDataSource that the GridView is bound to. The ObjectDataSource's insert parameters are populated in the handler for its Inserting event. The code for all of this (abridged) looks like this:
Markup:
<asp:GridView ID="gvComplexRates" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="odsComplexMileageRates"
EnableModelValidation="True" ShowFooter="True">
<Columns>
[code]....
The first of these shows a tag of td. Which makes sense. The second shows text of "10" which is the content for the row above the footer.

This is bugging me. I have a "main" form named frmMain with a DataGridView object named objDataGrid.When a user double clicks on a row or clicks another button, I hide the main form, open a new form and want to reference the values in the row selected by the user but I keep getting an error when I try to access some, but not all, of the datagridview's properties.

In my datagridview you have to double click it (putting it into editing mode) in order to delete the contents of the cell. Is there a way to program it so i can delete the contents by just pressing the delete button when it is highlighted?

I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.
What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.

clearing cell contents within a DataGridView?I have a column with a list of names and would like to be able to make the whole column blank.I can currently achieve this (not the greatest) by clicking on individual cells and doing this ..
DataGridView1.CurrentCell.Value = " "
But rather than doing this I would like to be able to do every cell in the column, all at once. I'll put the code behind a button, so it can all be achieved by a single click.

I have a gridvidew (GV2). I want the user to be able to export the contents of this gridview to an excel spreadsheet for offline processing.Here is my subroutine:
Protected Sub ExcelButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ExcelButton.Click
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
[code]....
On clicking the ExcelButton I get the error message:
Control 'GV2' of type 'GridView' must be placed inside a form tag with runat=server.
The control GV2 is in fact inside:
<form id="form1" runat="server"></form>

For example I have Columns colIsDayOff (Checkbox), colStartTime(Time), colEndTime(Time)
What I need to do is if when my DGV loads the data if colIsDayOff is checked, then make the value of the Start and End time columns blank, invisible, or something.

I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.
