Visual Studio 2008 SP1 Data Source Windows Problem

mgthantzin — Thu, 01 Jul 2010 08:43:27 +0000

I haven’t used data source that much as I have been working on web projects for quite some time. Today, I gotta take a look at our previous Windows program and realized that nothing happened when I clicked ‘Show Data Sources’ or ‘Add New Data Source…’ from Data menu. I had to run this once to get it solved.

JavaScript pageLoad() for MasterPage and ContentPage

mgthantzin — Thu, 13 May 2010 16:03:27 +0000

Sometimes, we need to use pageLoad() function in both MasterPage and ContentPage to get something done. But, if we add two function with such same name, that function residing in ContentPage will be ignored by the browser. To correct this behaviour, we need to extend pageLoad() function in MasterPage as follows:

In MasterPage

function pageLoad(sender, args)
{
...
// ... do my MasterPage JavaScript stuff...
...
if (window.contentPageLoad) {
window.contentPageLoad(sender, args);
}
}

In ContentPage

function contentPageLoad(sender, args)
{
// do something
}

Adding external files to VS project

mgthantzin — Thu, 13 May 2010 16:00:51 +0000

Sometimes, we need to include files while publishing our web application in Visual Studio. But, those files (e.g. pdf) are not published together. In that case, make sure the file is in project. Right-click the file and if you see ‘Include in Project’, it means that file is not part of project yet. Then, right-click the file again. Select properties and set these values:

Build Action: Content
Copy to Output Directory: Do not copy (This is to copy the file to Bin folder.)

innerText for Firefox

mgthantzin — Thu, 13 May 2010 15:59:17 +0000

Firefox doesn’t recognise innerText property. Below is the fix.

var AmountLabelControl = document.getElementById('lblAmount');

var amount;

if (AmountLabelControl.textContent) {
// Firefox...
amount = AmountLabelControl.textContent;
}
else if (AmountLabelControl.innerText) {
// IE...
amount = AmountLabelControl.innerText;
}

IE8 renders blank sub menu items for ASP:Menu

mgthantzin — Thu, 13 May 2010 15:58:35 +0000

This is a known issue. Add following CSS class to your page.

.IE8Fix
{
z-index:100;
}

And, apply that CSS to your menu’s DynamicMenuStyle.

Simulating Button Click() Event in Firefox

mgthantzin — Thu, 13 May 2010 15:57:29 +0000

We cannot directly simulate click event in Firefox. Add the following code to register mouseclick event for the button.

HTMLElement.prototype.click = function() {
var evt = this.ownerDocument.createEvent(‘MouseEvents’);
evt.initMouseEvent(‘click’, true, true, this.ownerDocument.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);
this.dispatchEvent(evt);
}

Then, you may call the event in Firefox as if you do in IE.

For client-side button: document.getElementById(’btnUpdate’).click();
For server-side button: document.getElementById(’<%= this.btnUpdate.ClientID %>‘).click();

iFrame & Modal PopUp

mgthantzin — Thu, 13 May 2010 15:56:41 +0000

Undesired Behaviour: I tried to call a ASP.Net Ajax Modal Popup from master page code and child page has got one HTML iFrame. Modal Popup didn’t appear while the code was executed.

Fix: Add runat=”server” tag to iFrame and make it server-side element. Behaviour was corrected.
