Why dont you use your custome validator?it will be best for your scenario

Iterate through Control collection of the page and then check for Text box validation.

Hi Friends,
I need a help.In my application i set the connectionstrings and all settings in webconfig file.But anyone can edit teh webconfig.Is there any option to protect the webconfig editing in .net application as in access database.If anyone tries to edit the webconfig ask username and password.If the entered username and password is correct only the user have to edit the whole webconfig.
Send some queries to solve it.Because after publishing alos if anyone tries he can simply edit the webconfig.So i think in this way.

Does he has access to the server in which your application is hosted ?
Its impossible to access the web config and machine config file from browser...

Not from the browser sir.If anyone open the config file in the application ask username and password first and if both are correct only he can edit the config files in the application.
|
|
|
|
|
|
Thanks for your kind reply sir.Actually my question is not that.We can secure the access database file by setting username and password.When anyone tries to open the file they ask password.Like that is there any way to secure my webconfig file in an application.If anyone tries to open the config file ask password(not in browser) and if teh password is correct only he can open the config file.Please i need that secureation.Not encrypting teh connectionstrings and not.

If your server is properly secured you shouldn't have this problem. Make sure that only the relevant personel can log in to the server, or if it is shared, restrict write access on the web.config file to specific users using standard windows security.

In my application I want to call a java script in a button click at the code behind.And the button is inside an update panel.But the java script is not working.If i place the button out side the update panel then it is working.My question is how to call the java script by placing the button inside the update panel?
|
|
|
|
|
How are you registering your javascript call? You might want to try ScriptManager.RegisterStartupScript, as this will be called following a callback.
|
|
|
|
|
I have already used it but still not working.
|
|
|
|

Have you added your button control inside the <triggers> tag of the Update panel...
and one more thing you also need to know whether it is a post back trigger or asynchronous trigger...
If you are not aware of this, Just try this the following piece of code
<Triggers>
<asp:postbacktrigger controlid="Your Button Name">
<asp:asyncpostbacktrigger controlid="Your Button Name" eventname="Click">
</Triggers >

Hello everyone,
I have a gridview,in which each row populates a question with its answers(as radio buttons). I have to execute some code on radio button's OnCheckedChanged event.Somehow,on its OnCheckedChanged event,page is postbacked but it is not going to OnCheckedChanged() method.Can anyone give any suggestions for how can I achieve this?
The code looks somewhat like this :
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:GridView ID="GridView1" OnRowDataBound="GridView1_OnRowDataBound" AutoGenerateColumns="false"
runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView2" AutoGenerateColumns="false" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="true" OnCheckedChanged="RadioButton2_CheckedChanged" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
|

|
|
Clean Solution and then Rebuild.
|
|
|
|

Thanx for your reply,but I have already tried doing this. In fact,I created a separate project just to check whether it works or not,but it still failed.
The same method I called on a button's OnClick & it worked but it didn't work for RadioButton's OnCheckedChanged().

Since you have defined the control inside grid u have to create the checked event, ex-
<asp:GridView ID="grdSearch" runat="server" Width="100%">
<Columns>
<asp:TemplateField HeaderText="FirstName">
<ItemTemplate>
<asp:LinkButton ID="lbtnFName" runat="server" Text='<%# eval("fname") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Code behind-
Protected Sub grdSearch_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdSearch.RowCreated
Dim LinkButton1 As LinkButton
Select Case e.Row.RowType
Case DataControlRowType.DataRow
LinkButton1 = CType(e.Row.FindControl("lbtnFName"), LinkButton)
AddHandler LinkButton1.Click, AddressOf lnkApptBtn_Click
End Select
End Sub
'Handler function
Protected Sub lnkApptBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim lngPcpid As Long
Dim lnkbtn As LinkButton = CType(sender, LinkButton)
Dim objItem As GridViewRow = CType(lnkbtn.Parent.Parent, GridViewRow)
Dim intSelectedRow As Integer = CInt(objItem.RowIndex.ToString())
lngPcpid = Trim$(grdSearch.Rows(intSelectedRow).Cells(4).Text)
End Sub
U just have to change the link button event to radio button event
All the best
