ASP.NET Grid view Data filed Column Formatting Not working

I have a problem with the GridView column formatting.
I have a PhoneNumber that is currently coming from database as (###)###-#####
but I want the format to be ############ without spacing and brackets. I have tried every thing like DataFormatString="{0:###-####}" or than converting it into TemplateField and giving it format but not working.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" >
<Columns>
<asp:TemplateField HeaderText="Phone Number">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%#
Bind("PhoneNumber") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("PhoneNumber", "{0:d}") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
This is before converting the column to TemplateField:
<asp:BoundField DataField="PhoneNumber" HeaderText="Phone Number Home"
SortExpression="Phone" DataFormatString="{0:######-####}" HtmlEncode="false" />
But nothing is working. I still get the format of phone number like this (123) 123-4567.

If you are dynamically binding the rows in code behind, you should be formatting the columns in the DataBind event of the gridview.
The semantical column formatting works only when you use bind data semantically, for example declare

Try to replace Text property in TemplateField:
Text='<%# Bind("PhoneNumber", "{0:d}") %>'
with:
Text='<%# String.Format("{0:##########}",
Convert.ToInt64(DataBinder.Eval(Container.DataItem, "PhoneNumber")))%>'
Use "#" Custom Specifier.

Formatting is solely additive, not subtractive. To accomplish this, you would need to expose a version of the values which has non-numerics stripped out, so that your client-side formatting can act upon it.

aspx bind data with '#' symbol to gridview

Been trying to fix this for hours and I know that the problem is with the '#' but I could not find any solution to this problem. My field name in the database is 'HRTRN#'.
<asp:TemplateField HeaderText="Transaction#">
<EditItemTemplate>
<asp:TextBox ID="TextBox13" runat="server" Text='<%# Bind("HRTRN#") %>' Width="50px" Height="17px" MaxLength="14"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%# Bind("HRTRN#") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Does anyone know the solution for this to make the field name containing # symbol accessible?

You should change your code from :
Bind("HRTRN#")
To
Bind("[HRTRN#]")
Since it contains special charcters. ( you would do that also for columns with spaces).

ASP.NET C# BoundField format (Remove leading zeros)

How should DataFormatString of BoundField in Gridview look like that values won't have leading zeros?
So far I got this:
<asp:BoundField DataField="NUMBER" HeaderText="Id. number" DataFormatString="{0:d}">
Expected result:
000001 -> 1
002101 ->2101
I tried to figure that problem out with official documentation and this page. So far unsuccessful.

When you want to format something properly in a boundfield, I always suggest converting it to a templatefield. It's much easier to work with than boundfields. Here is an example of how the templatefield will look like once it's converted.
<asp:TemplateField ShowHeader="False" Visible="False">
<EditItemTemplate>
<asp:TextBox ID="tbEditNumber" runat="server" Text='<%# Bind("Number","{0:n}") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:TextBox ID="tbNumber" runat="server" Text='<%# Bind("Number","{0:n}") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
within that template field I placed..
Text='<%# Bind("yourfield","{0:n}") %>'
This should format it into a number and should drop the leading zeros.
EDIT: You might be able to try
Text='<%# String.Format("{0:n}", Eval("Number") ) %>'

Another approach is to use String.Trim function. The following code is how I accomplished what you are trying to do:
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" Text="<%#Eval("NUMBER").ToString().TrimStart('0')%>" ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The tricky part was using the correct combination of quotes and single quotes. You can use
"
in place of the quote character around your datafield column that you are displaying.

Simplifiying A Kimmels answer, no need to place in a server label, no concern of single or double quotes, no concern of underlying datatype, as it casts the object to string, then performs a string.TrimStart, no need for codebehind
<asp:TemplateField HeaderText="Work Order">
<ItemTemplate>
<%# Eval("WorkOrder").ToString().TrimStart("0".ToCharArray()) %>
</ItemTemplate>
</asp:TemplateField>
0123456 = 123456
0012345 = 12345
if a server label is required, just start and end the text tag with single quotes
<asp:Label ID="lblWorkOrder" runat="server" Text='<%# Eval("WorkOrder").ToString().TrimStart("0".ToCharArray()) %>' />

Try this. Much cleaner this way.
Markup
<asp:TemplateField HeaderText="Id. number">
<EditItemTemplate>
<asp:TextBox ID="tbEditNumber" runat="server" Text='<%# ConvertToDigit(Eval("Number")) %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:TextBox ID="tbNumber" runat="server" Text='<%# ConvertToDigit(Eval("Number")) %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
Code-behind
protected int ConvertToDigit(object oNum)
{
var i = 0;
if (oNum != null) int.TryParse(oNum.ToString(), out i);
return i;
}

How to wrap the DropDownList in the GridView FooterTemplate?

Please help me to fix the issue with wrapping the text in asp.net GridView FooterTemplate.
I am alyready wrapping <ItemTemplate> and <EditItemTemplate> using the below command
<asp:TemplateField ItemStyle-Wrap="true"
but the same code is not working for the FooterTemplate.
Please see the below code
<asp:TemplateField ItemStyle-Width="120px" HeaderText="Bureau" ItemStyle-Wrap="true">
<ItemTemplate>
<asp:Label ID="lblBureau" runat="server" Text = '<%# Eval("Bureau_Ref_Type")%>'
></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblBureauEdit" runat="server" Visible="false" Text = '<%# Eval("Bureau_Ref_Id")%>'></asp:Label>
<asp:DropDownList ID="ddlBureauEdit" runat="server">
</asp:DropDownList>
</EditItemTemplate>
<FooterTemplate>
<asp:DropDownList ID="ddlBureauFooter" runat="server">
</asp:DropDownList>
</FooterTemplate>
</asp:TemplateField>
If i reduce the size in the FooterTemplate Dropdowlist items text page seems to fit in 1024 px resolution,but our client wants the same resolution with out reducing the Item text size. So i need all experts to help wrapping the items in the FooterTemplate.
Thanks

You need to use the FooterStyle to style that section. Your ItemStyle settings only apply to actual data items (not footers or headers).
You could rewrite the first section of your markup like this:
<asp:TemplateField HeaderText="Bureau">
<ItemStyle Width="120px" Wrap="true"></ItemStyle>
<FooterStyle Wrap="true"></FooterStyle>
<ItemTemplate>
...
Notice that I moved your ItemStyle settings into the <ItemStyle> settings block, as well as adding the <FooterStyle> settings block.

Javascript Breaking on < & > in a GridView edit box

I've got an Asp.Net GridView inside an UpdatePanel. It all works fine, except when one of the columns includes HTML special characters like < and >. The GridView is bound to a List<Entity> and the Entity class has a property Regex which is a System.Text.RegularExpressions.Regex.
At first I had this:
<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Label ID="RegExLabel" runat="server" Text='<%#Eval("Regex") %>'
ToolTip='<%#Eval("Regex") %>' Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server" Text='<%#Eval("Regex") %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
With a value of (?<capture>\d+) this displayed ?\d+ when not editing, and when editing this row I got a script error and the edit, update and cancel buttons no longer work.
Then I tried the answer in this question and had this:
<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Label ID="RegExLabel" runat="server"
Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
ToolTip='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server"
Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
This is slightly better, in that the tooltip and the non-editing version display correctly, but when I start editing I see: (?<capture>\d+) with the HTML Entities displayed raw. Does anyone know a way to encode the values (to stop the script error) while still displaying them correctly without the HTML entities in their raw state when editing?

<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Literal Mode="Encode" ID="RegExLabel" runat="server" Text='<%#Eval("Regex") %>'
ToolTip='<%#Eval("Regex") %>' Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server" Text='<%#Eval("Regex") %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
and in the page directive add this ValidateRequest="false"
