Accessing And Renaming Text Block Inside Datagrid Column Header

Jul 22, 2013

I was using the VisualTreeHelper trying to locate a textBlock inside the datagrid columnHeaders. I have just learnt that : "The Header object of the DataGridColumn is actually the visible header of that column, whatever you set it to be. DataGridColumn is not part of the Visual Tree so there is not direct way to access the DataGridColumnHeader for it (we can't even be sure it exists yet)... " This has set me back by a couple of days. I tried to convert the suggested code to vb.net in order to use it but I don't seem to get it right. The code in c# is :

Code:

ataGridColumnHeader headerObj = GetColumnHeaderFromColumn(column);
private DataGridColumnHeader GetColumnHeaderFromColumn(DataGridColumn column)
{
// dataGrid is the name of your DataGrid. In this case Name="dataGrid"
List<DataGridColumnHeader> columnHeaders = GetVisualChildCollection<DataGridColumnHeader>(dataGrid);

[Code] ...

How to apply it in my scenario shown below. I want to access in order to rename the textblock 'columnHeaderName'. How can I do this?

Code:

<Datagrid>
<Datagrid.Columns>
<DatagridTemplateColumn Header="header1" Width="100">
<DatagridTemplateColumn.HeaderTemplate>

[Code] ....

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Forms Data Controls :: Gridview Column Formatting Depending On Text In Header?

Mar 30, 2010

I want if the header of a particular column contains a word "S", the header and row turns red. I used following code to make header red and it works fine. How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.

Protected Sub GridView1_DataBound(ByVal sender
As
Object,
ByVal e
As System.EventArgs)Dim HeaderRow
As GridViewRow = GridView1.HeaderRowFor
Each c
As TableCell
In HeaderRow.CellsIf c.Text.EndsWith("S")
Then
c.BackColor = Drawing.Color.OrangeRed

DataGrid Header Text Set Dynamically But Not Being Retrieved

Mar 26, 2014

I have a DataGrid defined with columns such as:

Code:
<asp:BoundColumn HeaderStyle-HorizontalAlign="Center" ItemStyle-Width="10%" DataField="MONTH_PREVIOUS_YEAR" HeaderText="Month Hours (Previous Year)" ItemStyle-HorizontalAlign="Right"></asp:BoundColumn>

At a certain point in my program, I successfully re-set some of the Header titles programmatically:

Code:
Private Sub dgAccountability_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgAccountability.ItemDataBound
If e.Item.ItemType = ListItemType.Header Then
Dim previousYear As Integer = (Integer.Parse(year) - 1)
e.Item.Cells(1).Text = "YTD Hours " & previousYear.ToString

Forms Data Controls :: DataGrid Freeze Header Code Not Working?

Feb 14, 2010

I have searched numerous articles for how to accomplish freezing the Header Row of a DataGrid or GridView component being to simply hide the header and then build table cells just above the component to define the columns. But the one that I'd like to get to work is by the use of CSS code. Problem is that this code seems to work for everyone else but it isn't working for me. Here's my Stylesheet code:

[Code]....

When I run my page I get all the styles applied but the header scrolls with all the other rows in the grid.

why this code is probably not working? I am using .NET Framework 3.5 and developing in VSS 2008 which may be why this doesn't work?

I have successfully downloaded sample code from Code Project which works using other techniques as well, but the code was written in .NET 1.1 Framework and VB.NET.

Forms Data Controls :: Datagrid Setting Background Color Depending On Header Value?

Oct 18, 2010

I have an asp.net gridview which represents some kind of reservation calendar. Each row represents a workplace and each column a day. The header value (date) is set by a method since the start of the time period shown by the gridview can be selected by the user. Since the date column can start at every day of the week I wanted to mark the weekend day columns with a special background. How to set this? (See .aspx code snippet below which is currently used for each column ().

Remark: ItemStyle-BackColor= '<%# %>' (dynamic) annotation isn't allowed in the <TemplateField> Tag and the actual date must be evaluated somehow from the header or another control.
