On clicking a link I want to call the same page(default.aspx). But I want to add the QueryString as < A href="/KB/answers/Default.aspx"?fg=5"> CLICK < /a>
The value 5 is got from a combobox.

How to add that value?

XML

I want to add the selected value of Combo to the href attribute of <a>

<dx:ASPxComboBox ID="ASPxComboBox1" runat="server" AutoPostBack="true" DataSourceID="SqlDataSource2"
onselectedindexchanged="ASPxComboBox1_SelectedIndexChanged" TextField="mnth" ValueField="mnth"></dx:ASPxComboBox>

<a href="Temp.aspx?mon=JUN14">CLICK</a></td>


ie, JUN14 should be the selected value of combo

Thanks in advance

Ok, but post also the part where you emit the code of the link itself.

< a href="/KB/answers/Temp.aspx"?mon="+selected value of combo >CLICK< /a>

Will not work. Because when the page is already rendered, there is no way to get the value from the combo and put it into the link unless you use Ajax or Javascript.

To do it in ASP.NET way, use an UpdatePanel. What updatePanel does is the partial update of a page. Follow the link to have an idea.
