Handling events in a datagrid

[Deepak]

Hi,
I am having a datagrid with 3 radiobuttons in one template column and a
textbox in another template column. How can I disable or enable the textbox
in the second template column depending on the value of the radio buttons?
I am also giving my datagrid for ur reference.

<aspataGrid id="MyDataGrid" runat="server" OnSortCommand="MyDataGrid_Sort"
AllowPaging="True"
PageSize="10"
BorderColor="black"
BorderWidth="1"
GridLines="Both"
autodraw = "False"
AllowSorting="true"
AutoGenerateColumns="false"
Width=100%

<columns>

<asp:templatecolumn headertext = "<font style='text-decoration:none'
color='#ffffff' Title='Click here to SORT' Title='Click here to SORT'>
Approve/Reject</font>" >
<ItemTemplate >
<font = "LHBoxFont">
<asp:radiobutton id= "rbtnApprove" GroupName ="a" runat="server" /> Pay
Claims

<br>
<asp:radiobutton id= "rbtnReject" GroupName ="a" runat="server" /> Reject
Claims
<br>
<asp:radiobutton id= "rbtnIgnore" checked="true" GroupName ="a"
runat="server" /> Ignore Claims

</font>
<itemStyle width = 15% Cssclass = lblHeader align=center>
</itemStyle>
</ItemTemplate>


</asp:templatecolumn>


<asp:templatecolumn headertext = "<font style='text-decoration:none'
color='#ffffff' Title='Click here to SORT' Title='Click here to SORT'> Paid
Date/Comments</font>" >
<ItemTemplate>
<asp:textbox id= "txtPayClaims" runat="server"/>
</ItemTemplate>
<itemStyle width = 25% Cssclass = lblHeader >
</itemStyle>
</asp:templatecolumn>

</columns>

</aspataGrid>


In the above scenario, I want to enable the textbox,"txtPayClaims", if the
value in the radiobutton, "rbtnApprove" is selected and must disable the
textbox if the value in the radiobutton, "rbtnReject" is selected .

Is there any way I can do this??

Thanks,
Deepak

You can attach OnCheckedChanged eventhandler to radio button and set its
autopostback property to true. Then in that eventhandler you can access the
textbox, so you disable or enable it depending upon the requirement. In the
event handler you can write code like this to access the text box

Dim oTextbox As TextBox

Dim oRadio As RadioButton

oRadio = CType(sender, RadioButton)

oTextbox = oTextbox.Parent.FindControl("txtPayClaims")

oTextbox.enabled = "Changed"
