I am getting this ~/Data/TestCopy.pdf for my Documents in the GridView but I am trying to get only the filename without the directory from SQL database. Does anyone know how to achieve this?
Thanks!
<asp:TemplateField HeaderText="Documents " SortExpression="filePath">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("filePath") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" Target="_blank" runat="server" Text='<%# Bind("filePath") %>'
NavigateUrl='<%# Eval("filePath") %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
The simplest way is, just add the Reference to System.IO and use Path class to get only the file name, little change in your code,
<asp:TemplateField HeaderText="Documents " SortExpression="filePath">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Path.GetFileName(Bind("filePath")) %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" Target="_blank" runat="server" Text='<%# Path.GetFileName(Bind("filePath")) %>'
NavigateUrl='<%# Eval("filePath") %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
In Gridview RowDataBound , evaluate filename from filepath.
System.IO.Path.GetFileName(filePath).
Not sure but you can try something like this:-
Text='<%# Eval("filePath").ToString().Split(Eval("filePath").ToString().LastIndexOf("/"))[1] %>'
May be you have stored it this way ~/Data/TestCopy.pdf in the database. You can use split function to split the last '/'

Currently my Gridview hyperlink is passing one parameter in URL as show below
<asp:HyperLink ID="hlnkREQUEST_ID" runat="server"
Text='<%# DataBinder.Eval(Container, "DataItem.REQUEST_ID") %>'
NavigateUrl='<%# "~/StudentPages/viewREQUEST_ID_page.aspx?REQUEST_ID="+DataBinder.Eval(Container, "DataItem.REQUEST_ID")%>' >
Now, in the same hyperlink I need to pass another parameter which I am adding like this:
<asp:HyperLink ID="hlnkREQUEST_ID" runat="server"
Text='<%# DataBinder.Eval(Container, "DataItem.REQUEST_ID") %>'
NavigateUrl='<%# "~/StudentPages/viewREQUEST_ID_page.aspx?REQUEST_ID="+DataBinder.Eval(Container, "DataItem.REQUEST_ID") & REQUESTER="+DataBinder.Eval(Container, "DataItem.REQUESTER")%>'>
but this is causing an error
"REQUESTER" does not exist in current context
What's wrong here?
You need to make changes:
<asp:HyperLink ID="hlnkREQUEST_ID" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.REQUEST_ID") %>' NavigateUrl='<%# "~/StudentPages/viewREQUEST_ID_page.aspx?REQUEST_ID="+DataBinder.Eval(Container, "DataItem.REQUEST_ID") + "&REQUESTER="+DataBinder.Eval(Container, "DataItem.REQUESTER")%>'>
I want to make one of the data bound in my gridview uneditable or in my case, I want to make the textbox in edit mode in read only. here is what I have tried but not successful:
TextBox ProductImage = GridView1.Rows[e.RowIndex].FindControl("TextBox1") as TextBox;
ProductImage.ReadOnly = true;
and here is the aspx code:
asp:TemplateField HeaderText="ProductImage" SortExpression="ProductImage">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("ProductImage") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ProductImage") %>' />
</ItemTemplate>
<ControlStyle Width="50px" />
</asp:TemplateField>
can someone help me out?
Have you tried setting ReadOnly to true in your aspx code?
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true" Text='<%# Eval("ProductImage") %>'/>
</EditItemTemplate>
Or you could use a Label instead of a TextBox
<asp:Label ID="Label1" runat="server" Text='<%# Eval("ProductImage") %>'/>
I'm using asp and have some textboxes where I want to set the value from code behind. The code below is wrapped inside an asp:DetailsView.
The Textbox I want to get and set value of is InsertItemTemplate with ID=strPositionsName
<asp:TemplateField HeaderText="Name" SortExpression="strPositionName">
<InsertItemTemplate>
<asp:TextBox ID="strPositionName" Width="380px" MaxLength="49" runat="server" Text='<%# Bind("strPositionName") %>'></asp:TextBox>
</InsertItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="Textbox1" Width="380px" MaxLength="49" runat="server" Text='<%# Bind("strPositionName") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Width="380px" Text='<%# Bind("strPositionName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
I managed to get the value by:
var testName = ((TextBox)DetailsView1.FindControl("strPositionName")).Text;
So I tried using this:
((TextBox)DetailsView1.FindControl("strPositionName")).Text = "textboxvalue";
But it didn't work
Try Following Code
TextBox _txtPositionName=(TextBox)DetailsView1.FindControl("strPositionName");
if(_txtPositionName!=null)
_txtPositionName.Text="textboxvalue";
Not able to DataBound the Style attribute
Style='<%# Eval("LeftPadding","padding-left:{0}") %>'
Full Code
<asp:TemplateField HeaderText="Report Item" SortExpression="ReportItem">
<ItemTemplate>
<asp:Label Style='<%# Eval("LeftPadding","padding-left:{0}") %>' ID="lblReportItem"
runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
</ItemTemplate>
<ItemStyle Width="350px" />
</asp:TemplateField>
But I can DataBound some other attributes even not a Standard HTML attribute, like below
<asp:Label StyleTemp='<%# Eval("LeftPadding","padding-left:{0}") %>' ID="lblReportItem"
runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
What is the problem with Style ?
Got Answer :)
<asp:Label Style=<%# string.Format("padding-left:{0}px",Eval("LeftPadding")!=DBNull.Value? Convert.ToString(Eval("LeftPadding")): "0") %>
ID="lblReportItem" runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
Tried by without giving the Single Quotes for the style attribute and used string.Format
Style=<%# string.Format("padding-left:{0}px",Eval("LeftPadding")!=DBNull.Value? Convert.ToString(Eval("LeftPadding")): "0") %>
I have a bound field in my Gridview which is getting its value from a database table.
I have got the data but don't know how to format it inside the gridview.
For example I get total data from below like "123456", but I want to display as "123,456"
<asp:BoundField DataField="totaldata" HeaderText="Total Data"
ReadOnly="True" SortExpression="totaldata" />
How can I do this? Do I need to convert the bound field into a template field ? But what do i do after that.
please help.
I have used DataFormatString="{0:n0}" and it solved the above problem.
how do i do for this:
<asp:TemplateField HeaderText="Failed Files"
SortExpression="NumFailed">
<ItemTemplate>
<asp:Image ID="Image2" runat="server" ImageUrl="~/NewFolder1/warning_16x16.gif" />
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
the hyperlink has the number which need to be formatted...
Use DataFormat property :
<asp:BoundField DataField="totaldata" HeaderText="Total Data"
ReadOnly="True" SortExpression="totaldata" DataFormatString="{0:n3}" />
EDIT : For the second part of your question use Eval method's second parameter to format your data :
<%# Eval("NumFailedFiles", "{0:n3}") %>
Then your template will be like that :
<asp:TemplateField HeaderText="Failed Files"
SortExpression="NumFailed">
<ItemTemplate>
<asp:Image ID="Image2" runat="server"
ImageUrl="~/NewFolder1/warning_16x16.gif" />
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>'
Text='<%# Eval("NumFailedFiles", "{0:n3}") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
A couple of ways in how you can do that
Option 1
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles","{0:n0}") %>'></asp:HyperLink>
Option 2
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx? id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles").ToString("N") %>'></asp:HyperLink>
Option 3
Create a method in the code behind page that returns the formatted number.
protected string GetFormatedNumber(object number)
{
if ( number != null )
{
return number.ToString("N");
}
return "0";
}
And call the method in your aspx page as below:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx? id="+Eval("MachineID") %>' Text='<%#GetFormatedNumber(Eval("NumFailedFiles")) %>'></asp:HyperLink>
I think you need to take a look at this MSDN article on How to Format Data in the DataGridView
if you want to format your data on gridview use "{0:n3}"
<asp:Label ID="label" runat="server" Visible="true" Text='<%#DataBinder.Eval(Container.DataItem, "data","{0:n3}") %>'></asp:Label>
