Events in a UserControl

Good Day All

Am using a Infragistic Ultragrid Control and in the Control there is no event RowDataBound, So i decided to add it. I right Clicked on the Control and went to Properties and clicked at the lightning sign for events and double clicked "DataBound" event and next to it i started coding my event like this

protected void ultraGridCycles_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //We're only interested in rows that contain data

        //Get a reference to the data used  to databound the row
        DataRowView drv = (DataRowView)e.Row.DataItem;
        if (Convert.ToString(drv["1"]) == "1")
        {
            e.Row.Font.Bold = true;
            e.Row.ForeColor = System.Drawing.Color.Gold;
        }
    }

}

The Compiler did not complain. Now i want to use this event in the like in MS Gridview. How do i get that event to be Fired ?

Thank you

You have to either have Excel installed on the server, or a free package Microsoft has that let's a server access the DLLs required. Can't remember what it's called, but it should give ya some Google key words.

am resizing the uploaded image and also adding the watermark, that code as follows, but now am saving the image into local path, i want to save this image into sql server database. how can i do that. can i get some source code for that.

int thumbWidth = 0;
System.Drawing.Image image = System.Drawing.Image.FromFile(cmdBrowse.PostedFile.FileName);
if (image.Width > 500)
{
thumbWidth = 500;
}
else
{
thumbWidth = image.Width;
}
int srcWidth = image.Width;
int srcHeight = image.Height;
Decimal sizeRatio = ((Decimal)srcHeight / srcWidth);
int thumbHeight = Decimal.ToInt32(sizeRatio * thumbWidth);
Bitmap bmp = new Bitmap(thumbWidth, thumbHeight);
System.Drawing.Graphics gr = System.Drawing.Graphics.FromImage(bmp);
gr.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
gr.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;
gr.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;
System.Drawing.Rectangle rectDestination = new System.Drawing.Rectangle(0, 0, thumbWidth, thumbHeight);
gr.DrawImage(image, rectDestination, 0, 0, srcWidth, srcHeight, GraphicsUnit.Pixel);
Font font = new Font("Verdana", 14, FontStyle.Bold, GraphicsUnit.Pixel);
Color color = Color.FromArgb(100, 0, 0, 0);
Point pt = new Point(2, 3);
SolidBrush sbrush = new SolidBrush(color);

Ok. Instead of saving the bitmap into a file, save it to a memory stream and get the bytes from it to save to database. You need to use the other overload of Save which takes a Stream. GetBuffer[^] method will give you the byte array which can be saved to database then.

Add control in UpdatePanel

Hi.
I have an UpdatePanel in a UserControl that there is a button on it.
By clicking the button I want to add a control (textBox) dynamically to my WebForm.
but it doesn't work.
If I remove the UpdatePanel that works, but with UpdatePanel Not.
What can I do?

Best wishes

So, am I right in saying that your button is doing a postback and your page is reloading(no ajax)? If this is the case then I think it's the Triggers section of the UpdatePanel that you're missing. See my sample code below (you can ignore the content, it's just a report I knocked up). I've made bold and italic the Triggers section I think you could be missing. Also, the code where your dynamic control will be added will have to go in the ContentTemplate section of your UpdatePanel.

My apologies if I've missed the point and you're already doing this.

    <asp:Button ID="btnRun_TopHopFaults" runat="server" Text="Run Report"
        OnClick="btnRun_TopHopFaults_Click" />
    <asp:UpdatePanel id="pnlTopHopFaultsResults" runat="server" UpdateMode="Conditional">        
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="btnRun_TopHopFaults" />
        </Triggers>
        <ContentTemplate>                        
            <asp:Repeater ID="repTopHopFaults" runat="server">

There's a cryptography namespace in .NET. Your question actually has nothing to do with ASP.NET, you should nominate what language you're using and ask in that forum.
