Grid View Filter With TextBox/Grid View Filter With Passing Text  

If you require filtering gridview according to the text passing to it,then here is a solution.
here we are passing a column value via TextBox which will sort the column accordingly.

 <style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, Arial, Helevetica, sans-serif; color: #303933;}
Table.Gridview{border:solid 1px #df5015;}
.Gridview th{color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;padding:0.5em 0.5em 0.5em 0.5em;text-align:center}
.Gridview td{border-bottom-color:#f0f2da;border-right-color:#f0f2da;padding:0.5em 0.5em 0.5em 0.5em;}
.Gridview tr{color: Black; background-color: White; text-align:left}
:link,:visited { color: #DF4F13; text-decoration:none }
.highlight {text-decoration: none;color:black;background:yellow;}
</style><style type="text/css">

</div>
<asp:SqlDataSource ID="dsDetails" runat="server" ConnectionString="<%$ConnectionStrings:ThreadTestConnectionString %>" SelectCommand="select * from tbl_Currency" FilterExpression="currencyname LIKE '%{0}%'">
<FilterParameters>
