servercontrols

I'm trying to do what I thought was a very simple operation to set a property on an ASP.Net LinkButton control but for some reason ASP.Net is ignoring the tags and just passing through the value as a string. <asp:LinkButton id="viewDetails" runat="server" Text="Details" OnClick="btnDetails_Click" CommandName="ItemID" CommandArgument="<%= item.ItemID %>" /> When the link is clicked I handle it with: protected void btnDetails_Click(object sender, EventArgs e) { try { LinkButton btn = (LinkButton)sender; if (btn.CommandName == "ItemID") { string itemID = btn.CommandArgument.ToString(); } } catch

I have a custom server control with a property of Title. When using the control, I'd like to set the value of the title in the aspx page like so: <cc1:customControl runat="server" Title='<%= PagePropertyValue%>' > more content </cc1:customControl> When I do this, however, I am getting the exact String <%= PagePropertyValue%> being displayed rather than the Property Value that I would like to see. So after trying the databinding expression (as suggested below). I don't get the string literal that looked bad but I don't get anything else either. <cc1:customControl runat="server" Title='<%#

I'm using my code-behind page to create a save button programmatically: Button btnSave = new Button(); btnSave.ID = "btnSave"; btnSave.Text = "Save"; However I think this must create an html button or perhaps needs something else as I cannot seem to set the OnClick attribute in the following line, I can specify OnClientClick but this isn't the one I want to set. Button btnSave = new Button(); btnSave.ID = "btnSave"; btnSave.Text = "Save"; btnSave.Click += new System.EventHandler(btnSave_Click); protected void btnSave_Click(object sender, EventArgs e) { //do something when button clicked. }

I have a custom ASP.NET server control CustomControl with a property attribute Path . If the Path is not explicitly specified, then I want an exception to be thrown. For example, <myControls:CustomControl Path="somedirectory/someotherdirectory/somefile.ext" runat="server" /> should compile, and <myControls:CustomControl runat="server" /> should throw an exception. I realize I can do this in the getter of the Path property, but is there some attribute that necessitates this? Update Is there any mechanism for validating the values of the property attributes other than using in the getter methods

How do I get the ID of a server control with jQuery? E.g. I have <asp:Label ID="label1" runat="server""></asp:Label> and now I want to get "label1", var id = ?? If you use ASP.NET 4.0 you can set attribute ClientIDMode="Static" and your code will looks following way: <asp:Label ID="label1" runat="server" ClientIDMode="Static"></asp:Label> js: var id = 'label1'; var labelID = $('#<%= label1.ClientID %>'); You need to get the client ID. If you just need the ID, and not the actual value of the control, then you don't even need jQuery. var labelID = '<%= label1.ClientID %>'; Roman var $lblObj = $(
