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.
With reference to the following link: [URL] .....
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 am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.SelectedRow.Cells[5].Text;
TextBox1.Text = s.ToString();
//string s2 = GridView1.SelectedIndex.ToString();
//TextBox1.Text = s2.ToString();
}
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'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.
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)

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.

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.

View 3 RepliesI am able to get the values of GridView cells when the columns are not visible.
For Example:
<asp:BoundField DataField="TemplateKey" Visible="false"/>
foreach (GridViewRow gvrow in GridView1.Rows)
{
gvrow.Cells[0].Text.ToString()
}
But if I make the BiundFiled Visible="true" then I get the value in the code behind.
I do not want to show this value to the user and also want to get the value in the code behind. How can I do that?
we're creating a GridView to display news articles programmatically (not using a SQL database).
We can create & display the GridView, but are having a devil of the time to get the hyperlinks in SetupGrid() attached to the titles
of the articles in the GridView. Below is our .aspx code and .vb code of how we create the GridView. Any ideas on what we should do to get the hyperlinks array of strHyperlinks() in SetupGrid() to be applied to the titles in column 1 of the GridView?

I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.

I have a GridView known as GV_R001 with IssueType, ActID, IssueID cells. I want to Merge the similar IssueType cell accordingly. How do i merge and also sort the IssueType cell accordingly. The following is my codes:
Protected Sub GV_R001_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GV_R001.DataBound
For rowIndex As Integer = GV_R001.Rows.Count - 2 To 0 Step -1
Dim gvRow As GridViewRow = GV_R001.Rows(rowIndex)
Dim gvPreviousRow As GridViewRow = GV_R001.Rows(rowIndex + 1)
Dim cellCount As Integer = 0
If gvRow.Cells(cellCount).Text = gvPreviousRow.Cells(cellCount).Text Then
If gvPreviousRow.Cells(cellCount).RowSpan < 2 Then
gvRow.Cells(cellCount).RowSpan = 2
Else
gvRow.Cells(cellCount).RowSpan = gvPreviousRow.Cells(cellCount).RowSpan + 1
End If
gvPreviousRow.Cells(cellCount).Visible = False
End If
Next
End Sub
Apart from that, after sorting i want to calculate the amount of IssueID are in a particular IssueType and display in a cell called "Total". Is it possible to do so? By the way, I am using Web Developer 2008, VB.net.
I have a GridView (it could just as easily be a ListView if the latter is easier).
I have a Button completely outside of the GridView.
I want to access the cell values in the GridView from the Click event handler of the Button.
I have a Gridview with some cells in numbers while in some cell they could be null without numbers. I need to modify it such that the numbers in the Gridview are in these formats:-
(a) If it is 12345.333 becomes 12,345
(b) If it is blank, I wish the cells to display 0
This is the code I am using to achieve (a), but when it comes to blank, it returns error (I believe my code below failed to provide blank cases but I dunno how. So what should be the code to do (b) above ?
For i As
Integer = 1
To N
e.Row.Cells(i).Text = String.Format("{0:#,##0}", Convert.ToDouble(e.Row.Cells(i).Text))Next
