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?
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 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.
My gridview look like this,
Play Download SongName Date
button button 5/4/08
button button dala.mp3
button button gaima.mp3
*button - play button and download button,
Now I need to remove the space in the first row, i.e my grid view should look like
Play Download SongName Date
button button dala.mp3 5/4/08
button button gaima.mp3
button button lada.mp3 6/4/08
button button imasla.mp3
I have a GridView which works perfect when it is not empty. Now when the source is empty I want to show an empty GridView and to be able to insert rows inside.
I have this code for the page_load event:

I have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.
I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:
For count = 0 To GridView1.Rows.Count
If (GridView1.Rows(count).DataItem("Student Name").Equals(dtDataTable.Rows(count).Item("Student ID"))) Then
lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."
I want to insert Data Rows into Gridview from web page and I want to send the Inserted Row to Database table.
So I have 3 columns to insert the row.
I added itemtemplate & fotter template with textbox control for each column Inside Templatefield.
I added two buttons [Insert & Cancel buttons ] in fotter template to insert the row in Gridview.
After debugging the page I can't see gridview in my webpage. i can see only EdItdatatemplate items only.Why ?
Can you look at my code & me to insert the records in gridview..
.aspx page,
[Code]....

View 2 RepliesIs there a way I ignore all gridviews events (sorting, paginating) when using the back command (history.back)?
For example:
The user is sorting my grid and when he presses the back button or a link with history.back he goes to the previous page, not the previous grid state.
Im not using ajax or update panel, Im not allowed to. It's a regular grid in an aspx.
i'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.
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

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.
CellPadding only applies the padding to the header row. CssClass in Gridview, RowStyle or EditRowStyle has no effect.

One table contains 9 columns and other contains 40 columns... for example....see the below.
Insert/Edit RoleUID RoleID Role Desc ....etc columns
Here RoleId, role are mandatory fields... i am making those two with "*" red color. but if i click on the "INSERT" then i need to get a alert msg that the roleid is mandatory.. you should enter in interger value, and if "role" is null then same like "Role is mandatory... plz enter character value"

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I'm working on a project in vb.net framework 2.0 and have a column that has server names. I have the accessdb sql setup to order by the db, what I would like to do is to have it look like the following picture below. I'm pretty stumped on how to do it as the methods I've found online haven't worked so well. Also just a small tid-bit the gridview is bound to a ddl which selects the application and the gridview refreshes with server data. Country would be server name and state would be the environment.
