I am using a GridView on my ASP.NET form.
Would it be possible to have a GridView with 10 empty rows, having 5 columns.
Can I define the number of GridView Rows I could Edit.
i would then have an Update Button, which would update all the rows to the database.
I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

why i am getting a empty string for "GridView1.Rows[rowIndex].Cells[2].Text"?
When retrieving values from Gridview empty cells, you will get " " instead of a empty string or null.
Someone once change the columne's properties as following, but it doesn't work
ConvertEmptyString > true
HtmlEncode > false
HtmlEncodeFormatString >false
One solution is to check if the cell value is " ". If so, assign it an empty string. But this approach looks awkward.
I'm looking for a technique to edit a whole column (vertical) instead of a row (horizontal).Suppose i have 10 rows en 5 columns (like in Excel), and i want to edit all digits from different students (rows) for test number 3 (column).

I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?

I have a form that contains a asp:Table and it contains 2 rows with 6 columns.
Also on my form is a gridview. It contains one row with 6 columns. (see pic)
I'd like to see if I can format both so that they appear to have the same over-all width and cell width too.
I'd like to know if it's possible to do this in the source view - rather than programmatically.
In the pic, the top is the grid view and underneath is the table.
I bind data to GridView from SqlDataSource. GridView have <19 rows. But i want that all 19 rows are written. If Rows in SqlDataSource are empty it's must be empty in GridView but must be there!
View 2 Repliesi'm trying to check for an empty cell in a gridview.
On the RowDataBound event I tried the following:
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text.Trim()))
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text))
- if (e.Row.Cells[2].Text == "")
None of them worked.
I'm using boundfields. I can't use a TemplateField with a label because I need to check for other stuff for that column in the RowDataBound event by doing e.Row.Cells[2].Text - that only works if I use boundfields.
I am trying to show the footer template of a gridview on page load when there is no data in the database. The reason why im saying page load is that I have code to actually pull data from the database instead of a datasource.

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.
.I have a GridView, a PopupExtender and a Button (button is located next to the GridView). The GridView has textboxes and dropdownlists. Initially, the GridView has one empty row (i.e. the textboxes are empty, and the dropdownlist show "blank" option.)When you click on the button "AddFlowButton", a Popupextender shows up, with several textboxes and dropdownlists, and two Buttons ("AddCashFlowButton" and "CancelButton"). Once you fill out the PopupExtender, and click the "AddCashFlowButton" button in the extender, the GridView is populated using the values in the PopupExtender.The problem now is that when I click on the edit button next to a GridView row, the GridView becomes empty, i.e. the textboxes become empty and the dropdownlists show empty values.Here is the code:
ASPX:
<asp:UpdatePanel ID="UpdatePanel3" runat="server">
<ContentTemplate>
<asp:Panel ID="FlowPanel" runat="server" CssClass="modalPopup">
<table>
<tr valign="top">
<td>
Name
