Did you specified the event with gridview in aspx page ?

ok, there were two events for the same thing, that why it wasn't triggered. Now its triggered, but for some reason when I am stepping in to the code the label property doesn't get the text. Its left empty.
Here is the code:

void gvOrderProductVariants_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           Label lblFirstName= (Label)e.Row.FindControl("lblFirstName");
           if (lblFirstame.Text.Contains("John"))
               lblFirstName.ForeColor = System.Drawing.Color.Red;
       }


   }

Please tell me if I am doing something wrong.
Thx, Laziale

hi,

Here is an example:

gridview_OnDataBound(){
Label label1 = e.Item.FindControl("lable1") as Label;
Label label2 = e.Item.FindControl("lable2") as Label;
if(lable1.Text == "1") {
label2.ForeColor = "red";
}else if(lable1.Text == "2"){
label2.ForeColor = "blue";
}
}

Hope it helps Smile | :)

I can't get to the 'e' argument since the databound event is using EventArgs. Frown | :(

Thanks for your help though

<asp:SqlDataSource ID ="myid" ConnectionString = "server = .\sqlexpress; integrated security = True; database = northwind;"
SelectCommand = "select LastName from employees " runat = "server" />
<asp:BulletedList runat="server" DataSourceID = "myid"/>

and its output

* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView
* System.Data.DataRowView

i want it to be LastName not its default ToString();

You are missing DataTextField binding.

Specify the control's DataSourceID property. Specify at the very least the required DataTextField. The value of each record in this field will then be displayed as the text of each item in the list.

So, you need to do:

<asp:BulletedList runat="server" DataSourceID = "myid" DataTextField="LastName" />

Also set DataTextField of your BulletedList, because without it,How BulletedList list come knowthat what to show.Use following code

<asp:BulletedList runat="server" DataSourceID = "myid" DataTextField="LastName"/>

Let me know if still face problem.

A generic error occurred in GDI+ on bitmap.save

Hmm... that may be and sometime it's happens too. But that does not mean that you vote the post "1" without any reason (If you voted).
Thumbs Down | :thumbsdown:

Hi,

I'm trying to solve this issue for 1 week, and i can't seems to solve it.

I search through net, they say its most probably because of permission access.
I have given full rights for all the users, including "Everybody", but error still remains.

This error only will occurs after upload twice, or 3 times, or on the 5th file of uploading. Its random. So i suspect its not the permission access problem.

Below is summary of my codes.

System.Drawing.Image image = ResizeImageImg(fp.PostedFile.InputStream, ImageWidth, ImageHeight);<br />
image.Save(savepath, ImageFormat.Jpeg); // ERROR RAISE HERE<br />
<br />
image.Dispose();

private System.Drawing.Image ResizeImageImg(Stream streamImage, int maxWidth, int maxHeight)<br />
{<br />
    Bitmap originalImage = new Bitmap(streamImage);<br />
    int newWidth = originalImage.Width; // 148px<br />
    int newHeight = originalImage.Height; // 170px<br />
    double aspectRatio = (double)originalImage.Width / (double)originalImage.Height;<br />
<br />
    if (aspectRatio <= 1 && originalImage.Width > maxWidth)<br />
    {<br />
        newWidth = maxWidth;<br />
        newHeight = (int)Math.Round(newWidth / aspectRatio);<br />
    }<br />
    else if (aspectRatio > 1 && originalImage.Height > maxHeight)<br />
    {<br />
        newHeight = maxHeight;<br />
        newWidth = (int)Math.Round(newHeight * aspectRatio);<br />
    }<br />
<br />
    System.Drawing.Image CropedImage = new Bitmap(newWidth, newHeight);<br />
    using (Graphics grp = Graphics.FromImage(CropedImage))<br />
    {<br />
        grp.SmoothingMode = SmoothingMode.HighQuality;<br />
        grp.InterpolationMode = InterpolationMode.HighQualityBicubic;<br />
        grp.PixelOffsetMode = PixelOffsetMode.HighQuality;<br />
        grp.DrawImage(originalImage, 0, 0, newWidth, newHeight);<br />
<br />
        grp.Dispose();<br />
        originalImage.Dispose();<br />
    }<br />
<br />
    return CropedImage;<br />
}

Please help guys. If you do have any simple working codes, please share.

Thx.

Ok, could you tell us what error is being raised and have you debuggd to ensure that savepath and Image are valid objects when being passed at that point?

www.regexlib.com has multiple regular expressions that'll do what you want, pick one.

Since you know that ',' (Comma) is going to be the separator, use it and split the input and get an array of email id's. Then use regular expression on each email id to check it. Here is the sample code to do it:
