Hi all,
I have a TextBox and Button.
The Button have two events 'OnClentClick'(javascript) and 'OnClick'(server side).
OnClientClick of button i could able to set the value to textbox and i could see the value in TextBox.
But when OnClick of Button i could not able to read the changed value of TextBox. Its giving value which i assigned at design time. But i could see the new value in textbox. Why? whats the reason.
How to read that changed value on OnClick(Server Side].
Please suggest me how to do that.
Thanks in advance.

Beacuse field value set by javascript it not available in server side code
but you can access value by classical asp pattern
string txtvalue = request.form("fieldname")

The website contains the login controls which seems to work correctly. i.e. logging in with login details and showing the correct links accordinly...
Question:
How do I make sure on Logout, the user is presented with the Login screen? At present It shows Login or logout. In addition I would like to make sure if the user is not logged in, then he can not browse using the URL. And even if he tries to use the URL, then to see the Login screen.
Thanks

When your User logs in store the Username to the Session variable and change the login to logout and Change the Icon if you are using icons. When the user logs out set the Session that stored Username to an empty string or use Session.Abondon. Now on page load to have the Correct info Displayed, Check the Session is its not null , if its null then change the the label to logine else to logout.

or
Session["Username"].Abondon();

Hello,
I think this is an easier way by placing it in the web.config accordingly
<location path="AddCodes.aspx">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>

Have something like this:
1. Successful login, set a session variable with the username.
2. On logout link click, set that session variable as -1 and redirect to login page.
3. Set the default value of that session variable as -1 and place a check in all the pages that if that variable is -1, redirect to login page.
PS: Not an ASP.Net developer so there might be far better ways of doing this.

using Session, when login, Session["Username"]="##",
when logout, Session["Username"] = "".
You can check whether Session["Username"] is null to see if the user logged in or not. If Session["Username"]=="", the user didn't log in.

Good Day All
i have a Telerik Grid , i think the idea is the same as Normal asp.net grid. its Defined like this
<telerik:RadGrid ID="RagCategories" runat="server" Height="399px" Width="698px" AutoGenerateColumns="False" Skin="Sunset" OnDataBound="RagCategories_DataBound">
<MasterTableView>
<RowIndicatorColumn>
<HeaderStyle Width="20px"></HeaderStyle>
</RowIndicatorColumn>
<Columns>
<telerik:GridTemplateColumn DataField="CategoryID" HeaderText="ID" UniqueName="TemplateColumn">
<ItemTemplate>
<asp:Label ID="lblID" Font-Bold="true" runat="server" Text='<%# Eval("CategoryID")%>' ></asp:Label>
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="Forum Categories" UniqueName="TemplateColumn1">
<ItemTemplate>
<asp:HyperLink id="link1" Text='<%# Eval("CATEGORYNAME")%>' NavigateUrl='<%# Eval("[LINK]")%>' runat="server" > </asp:HyperLink>
<asp:Label ID="descr" runat="server" Text='<%# Eval("Description")%>'></asp:Label>
</ItemTemplate><HeaderStyle Font-Bold="True">
</HeaderStyle>
</telerik:GridTemplateColumn>
</Columns>
<ExpandCollapseColumn>
<HeaderStyle Width="20px"></HeaderStyle>
</ExpandCollapseColumn>
</MasterTableView>
<FilterMenu EnableTheming="True" Skin="Sunset">
<CollapseAnimation Type="OutQuint" Duration="200">
</CollapseAnimation>
</FilterMenu>
<ClientSettings>
<ClientEvents OnRowClick="OnClientClick="javascript: return SetHidSelectedRows()"" />
</ClientSettings>
</telerik:RadGrid>
in this Grid there is "CategoryID" and on RowDatabound event i hide this Column and it working. now in this Grid i have this
<asp:HyperLink id="link1" Text='<%# Eval("CATEGORYNAME")%>' NavigateUrl='<%# Eval("[LINK]")%>' runat="server" > </asp:HyperLink>
as shown above,when my user clicks the Hyperlink in the Grid, this will take the user to the Appropriate Page,its Good , and i want to save the "CategoryID" of the select Hyperlink.
Thank you

For example if I select the third row of the grid and on clicking the up arrow the third row should move to the second row and the data in the second row should move to the third.
thank you
