GridView TemplateField emplty cells

1 New Member
Dear GridView Experts!
I have problems with GridView when adding a column using TemplateField.
I fill GridView1 from a stored procedure. It has a Select statement and returns 14 columns, AutoGenerateCol umns="True".
When I add two columns manually to be able to start drag and drop, the drag and drop works OK, but in GridView1_PreRe nder() and GridView1_RowCr eated() I loose values of GridView1.Rows[i].Cells[2].Text and e.Row.Cells[3].Text, these are "". The e.Row.Cells.Cou nt gives the correct 16, but the cells are "". It is strange, that the grid appears correctly with all the values.
My problem is that I need to set colors based on the Status and Date fields in GridView1_PreRe nder() or somewhere else. Can anybody help me?
Thank you in advance.

private void SetTaskCalendar ()

GridView1.DataS ourceID = "ObjectDataSour ce1";
GridView1.DataB ind();

protected void GridView1_PreRe nder(object sender, EventArgs e)
for (int i = 0; i < GridView1.Rows. Count; i++)
//Overdue Tasks (not Ready and not Accepted)
if ((Convert.ToDat eTime(GridView1.Rows[i].Cells[3].Text).Date <= DateTime.Now.Da te.Date) &
(GridView1.Rows[i].Cells[2].Text != "Ready") && (GridView1.Rows[i].Cells[2].Text != "Accepted") )
GridView1.Rows[i].ForeColor = System.Drawing. Color.Red;
//Ready Tasks
if (GridView1.Rows[i].Cells[2].Text == "Ready") GridView1.Rows[i].ForeColor = System.Drawing. Color.Green;

protected void GridView1_RowCr eated(object sender, GridViewRowEven tArgs e)
String ID = e.Row.Cells[3].Text;

<asp:GridView ID="GridView1" runat="server" AutoGenerateSel ectButton="True " OnPreRender="Gr idView1_PreRend er"
OnSelectedIndex Changed="GridVi ew1_SelectedInd exChanged" AllowSorting="T rue"

Welcome to The Scripts. It appears you inadvertently posted your question to the .NET Articles section of our site. I have taken the liberty of moving it to the .NET Forum, as that is the appropriate place to post questions.
Good luck with your problem,

I have a gridview control. In this grid view there is a column for the price of an item. Some of the prices have a dollar sign in front of it and some dont. How do I get rid of the dollar sign if it is in front of the value? My guess would be to use a template column but I dont know how to go about this. Any ideas? Below is an example of what the data looks like raw from the database: $456.95 200.89

When you use a SqlDataSource to hook up data to a GridView it seems to be to be very inflexible.

Hi, We are working on a gridview inside the gridview (parent-child) scenario. The data of child grid will depend on the data of parent. Objectives: 1.Add new row in parent grid after each row and add child grid into that row because the columns in child grid are same as parent grid and we want to align them with the cols of parent grid. 2. If there is data for child grid we show a plus image in the parent row (in the row above the...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
