Question
I need to set the content page default button. My code is like this:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"
defaultbutton="BtnSearch" defaultfocus="TxtSearchValue">
It is working fine, but my master page menu have one image button like chat, I can press the enter key to fire image button click event but it does not fire default button in content page.
How to handle this type of issue?
Solution
1) You simply have to do:
this.Form.DefaultButton = this.btnId.UniqueID;
OR
2) Using Javascript:
function clickButton(e, buttonid)
{
var evt = e ? e : window.event;
var bt = document.getElementById(buttonid);
if (bt)
{
if (evt.keyCode == 13)
{
bt.click();
return false;
}
}
}
And from the code behind:
ContentPage.Attributes.Add("onkeypress", "javascript:return
clickButton(event,'" + btnSearch.ClientID + "');");
OTHER TIPS
I solved a similar problem with the following code.
Thx: http://www.w3schools.com/aspnet/prop_webcontrol_panel_defaultbutton.asp
<form runat="server">
<asp:Panel runat="server" DefaultButton="bt1">
<asp:TextBox runat="server" />
<asp:Button id="bt1" Text="Default" runat="server" />
</asp:Panel>
</form>
Wrap all the asp.net controls and buttons inside the Panel and set default button property of panel with the id of a button.
Try this code
protected void Page_Load(object sender, EventArgs e)
{
this.form1.DefaultFocus = txtSearch.ClientID;
this.Form.DefaultButton = btnSearch.UniqueID;
}
this.Page.Form.DefaultButton = btnSave.ID;
