TextboxWatermarkExtender and Textbox with TextMode = Password

I managed to do this by setting the watermark stylesheet to overlay an image in the textbox.

You simply take a snapshot of how you want the watermarked textbox to look, save that, then set the watermark css of that textbox to a style that displays the image and aligns the text to the right (because otherwise it will still be visible)

It's very easy and works flawlessly.

The Textbox:

<asp:TextBox ID="Password" runat="server" CssClass="txtbox_login" Width="120px" TextMode="Password">

The Watermark (Set the WatermarkText property to anything you want, but just one character):

<ajax:TextBoxWatermarkExtender ID="txtWMark2" runat="server" WatermarkCssClass="watermarked_psw"TargetControlID="Password" WatermarkText="*" />

The StyleSheet (You MUST align the text to the right, otherwise it will still display over the image):

.watermarked_psw

{

color: White;

font-family: Tahoma;

font-size: 11px;

border: solid 1px #a9a9a9;

text-indent:2px;

vertical-align:middle;

text-align:right;

background-image:url(../images/psw_wMark.png);

background-repeat:no-repeat;

}

Textbox validate characters digits only - Desktop App

I wanted to let the user enter onlydigits in a Textbox and validate the characters when the types.
I came up with this:

private void numericUpDown_Count_KeyPress(object sender, KeyPressEventArgs e)
{
if ("1234567890".IndexOf(e.KeyChar.ToString()) > 0)
{
e.Handled = false;
}
else
{
e.Handled = true;
}
}

tell me if there's an easier way :)

The ConnectionString property has not been initialized

I had this error:

The ConnectionString property has not been initialized.

I have a MSI installer, that is installed in our QA environment.

It was working before, and suddenly, I only had this error.
Googled up a bit, all this info on how to get the connection string and all that.

I finally realized that I rebuilt the whole solution, but I didn't rebuild the Deployment project. After a rebuild ... everything back to normal.

#:-S

Hope this helps someone.

Gridview nowrap

What do you do when you have
AllowPaging="False" AllowSorting="False" AutoGenerateColumns="True" Width="800px" ShowHeader="true"

And it wraps all your data?

you add:

OnRowDataBound="GridView_RowDataBound"

and then:

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
for (int i = 0; i < e.Row.Cells.Count; i++)
{
e.Row.Cells[i].Attributes.Add("style", "white-space: nowrap;");
}
}

Monthname in C# (C Sharp)

I think there's no Monthname (like is asp for ex. - which is weird)

But this is easy:

DateTime swTest = new DateTime(2000, 11, 1);
Page.Response.Write(swTest.ToString("MMMM"));

Calling a server side from client's Javascript

Did you ever need something like calling a server side thing from client's? Javascript ... ?

I think this is an easy way of doing that:

Response.Write ( " < script language="javascript"> function SetPmoR_Id() { document.all('" + lkbPmoRepAdd.ClientID + "').click(); } < / script>")

//or:

ClientScript.RegisterClientScriptBlock(this.GetType(), "somethn", " < script type='text/javascript'> function whatdoyouwannacalit() { try {document.all('" + yourlinkbutton.ClientID + "').click();} catch(e){} } < / script>");

what do you think?

you think there's an easier way? comment!
