Hi,
I have a GridView with some values which are read from database.
I want to show them in persian.
This is my code :

C#

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="GroupId" DataSourceID="SqlDataSource1">
         <Columns>
             <asp:BoundField DataField="GroupId" HeaderText="GroupId" ReadOnly="True" 
                 SortExpression="GroupId" />
             <asp:BoundField DataField="<%=ToFarsi('ParentGroupId')%>"
                 HeaderText="ParentGroupId" 
                 SortExpression="ParentGroupId" />
             <asp:BoundField DataField="GroupName" HeaderText="GroupName" 
                 SortExpression="GroupName" />
         </Columns>
     </asp:GridView>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:dbtestConnectionString2 %>" 
            SelectCommand="SELECT * FROM [T_group]"></asp:SqlDataSource>

And my method :

public static string ToFarsi(string str)
   {
       string vInt = "1234567890";
       char[] mystring = str.ToCharArray(0, str.Length);
       var newStr = string.Empty;
       for (var i = 0; i <= (mystring.Length - 1); i++)
           if (vInt.IndexOf(mystring[i]) == -1)
               newStr += mystring[i];
           else
               newStr += ((char)((int)mystring[i] + 1728));
       return newStr;
   }

This is the error :
A field or property with the name '<%=ToFarsi('ParentGroupId')%>' was not found on the selected data source.

Solution 1

hi
The Data Filed values will check the Selected Column names which you are going to bind there is no column in this ID "<%=ToFarsi('ParentGroupId')%>"
thats why its listing that error

I think you have to figure out some other methods to Conversion now you are trying to Convert it from the Datagrid DataField itself...

I already answered this question about "Eastern Arabic Numerals", but Persian variant is a bit different, as described here:

http://en.wikipedia.org/wiki/Eastern_Arabic_numerals[^].

So the implementation could be a bit more complex but the idea is basically the same.

So, please see my past solution for Eastern Arabic:
Arabic number problem in asp.net[^].

My code is similar to your ToFarsi, just check it up.

You may need to fix this implementation to fix the Persian numerals. I could not figure out the mapping between Unicode code points and Persian variant of numerals, but it's possible that the mapping is not just the shift (ordering can be non-linear). Please use http://unicode.org/[^] to find out.

Convert the ParentGroupID BoundField to TemplateField and you should be fine

ASP.NET

<asp:templatefield headertext="ParentGroupId">
     <itemtemplate>
            <asp:label id="Label1" runat="server" text='<%# ToFarsi(Eval("parentid").ToString()) %>'>
            </asp:label>
     </itemtemplate>
</asp:templatefield>

Please mark the solution as accepted it you like it.
