Controls within asp:Table cannot be selected

Question

User-879727125 posted

I am unable to select anything within an asp:Table. For example with:

<asp:Table runat="server">
	<asp:TableRow>
		<asp:TableCell HorizontalAlign="Center" Width="300px">
			<asp:Button runat="server" Text="Move" ID="MoveButton"
				UseSubmitBehavior="False" />&emsp;
			<asp:Button runat="server" Text="ToTop" ID="ToTopButton"
				UseSubmitBehavior="False" />
			<hr />
			<p>This is my left side.</p>
		</asp:TableCell>
		<asp:TableCell>
			<p>This is my right side.</p>
		</asp:TableCell>
	</asp:TableRow>
</asp:Table>
<asp:Button runat="server" Text="Go" ID="Button1"
	UseSubmitBehavior="False" />

In the designer when I click on a control in the table I get:

In the source view if I click on the button in the table then the properties window does not have the lightening bolt at the top for the events. When I click on the Go button in both the designer and source views I get the events. I can add events by typing in the code but it seems to be a bug that the properties window does not list the events whereas it does when the control is not in a table.

This appears to have existed for a long time; see Visual Studio designer event problem | The ASP.NET Forums. Should I report it as a bug?

Hi Sam Hobbs,

The button inside the asp:Table could not be clicked in your desgin view, but it could be triggered as normal button.

The event format is the same as the normal button.

            <asp:Table runat="server">
                <asp:TableRow>
                    <asp:TableCell HorizontalAlign="Center" Width="300px">
                        <asp:Button runat="server" Text="Move" ID="MoveButton" UseSubmitBehavior="False" OnClick="Button1_Click"/>&emsp;
                        <asp:Button runat="server" Text="ToTop" ID="ToTopButton" UseSubmitBehavior="False" />
                        <hr />
                        <p>This is my left side.</p>
                    </asp:TableCell>
                    <asp:TableCell>
                        <p>This is my right side.</p>
                    </asp:TableCell>
                </asp:TableRow>
            </asp:Table>
            <asp:Button runat="server" Text="Go" ID="Button1" UseSubmitBehavior="False" />

        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Write("11111");
        }

result:

You could see that when clicking the button inside the Table, it triggers the event.

Besides, it seems that asp:Table control does not allow you to select other control put inside it because it is a control itselft (it is not a container).

Thank you Jenifer but I did not (intend to) say it cannot be used during execution. I did say controls, I used a button as an example but I said that controls within the table cannot be selected in design view. And I did say I can type the event into the markup.

I assume it is a bug. We should be able to select controls in a table in design view, he same as when they are outside the table.

Hi Sam Hobbs,

Yes, I think you're right. It seems like a Visual Studio's bug.

I suggest that you could go to https://visualstudio.uservoice.com/forums/121579-visual-studio-ide  and https://developercommunity.visualstudio.com/spaces/8/index.html to propose this issue.

Best Regards,

It has been reported in Controls within asp:Table cannot be selected - Developer Community.

The decision is:

In order to select the contents of a container control like asp:Table or asp:Panel, the Control (or rather its ControlDesigner) must support a feature called "editable regions" to tell the Design View which parts are selectable and editable. The asp:Panel control and some other containers support this feature, but unfortunately, the asp:Table control never has. The only way to edit the content of an asp:Table control is to edit it in Source View.
