Hi,
I got answer for this solution

I changed
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

to

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
in design page
Then i used follwing css

/* Div container to wrap the datagrid */
div#div-datagrid {
width: 420px;
height: 200px;
overflow: auto;
scrollbar-base-color:#ffeaff;
}

/* Locks the left column */
td.locked, th.locked {
font-size: 14px;
font-weight: bold;
text-align: center;
background-color: navy;
color: white;
border-right: 1px solid silver;
position:relative;
cursor: default;
left: expression(document.getElementById("div-datagrid").scrollLeft-2); /*IE5+ only*/
}

/* Locks table header */
th {
font-size: 14px;
font-weight: bold;
text-align: center;
background-color: navy;
color: white;
border-right: 1px solid silver;
position:relative;
cursor: default;
top: expression(document.getElementById("div-datagrid").scrollTop-2); /*IE5+ only*/
z-index: 10;
}

/* Keeps the header as the top most item. Important for top left item*/
th.locked {z-index: 99;}

/* DataGrid Item and AlternatingItem Style*/
.GridRow {font-size: 10pt; color: black; font-family: Arial; background-color:#ffffff; height:35px;}
.GridAltRow {font-size: 10pt; color: black; font-family: Arial; background-color:#eeeeee; height:35px;}

my aspx page is

<div id="div-datagrid">
<asp:GridView ID="gv5" Width="100%" runat="server" BorderStyle="Solid"
BorderColor="Navy" meta:resourcekey="gv5Resource1" UseAccessibleHeader="True">
<HeaderStyle BorderColor="Black" ForeColor="Black" BackColor="LightSkyBlue"
/>

<AlternatingRowStyle BackColor="Transparent" />

</asp:GridView>
</div>

Have you checked to see what the ImageType is ? You really have a column called ImageNumner ? Why are you hard coding the number ?

The image type is a image/pjpeg. I tried this too and it did not work.

Response.ContentType = dr["ImageType"].ToString();
Response.Expires = 0;
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write((byte[])dr["ViewImage"], 0, Convert.ToInt32(dr["ImageSize"].ToString()));

Response.End();

Wow - that makes sense.

Did you try writing the bytes to the file system and seeing if they are really a jpeg ? Have you tried more than one image from your DB ?

AJAX Timer not firing

I'm trying to get the AJAX timer control to work. There is a very simple example of this found here:

http://www.asp.net/ajax/documentation/live/tutorials/IntroToTimerControl.aspx

I followed the example yet the timer event never fires. What am I missing?
I'm using VS2005.

Christian Graus6-Feb-09 9:46

Your code is broken ? Is there a download with the sample, and if so, have you tried that ?

Why do people need the AJAX library just to put a timer in their pages ?

I do not want to use AJAX. How can a incorperate a timer on a page without AJAX?
Please refer to the link in the orginal question for the sample code.

Christian Graus6-Feb-09 9:52

AJAX is just javascript. AJAX exists without the stupid Microsoft AJAX toolkit. There is only one way to have a timer on a page - with javascript. The AJAX toolkit is just wrapping a very basic web dev task for you.

The ^ in my post is a link. Sorry, I dunno what happened, I just pasted and CP auto formatted, I must have hit space or something, I expected you'd see the URL as well as the ^ for a new window.

Did I miss the CP announcement that today was Rhetorical Question Day? Poke tongue | ;-P

The answer is that AJAX solves everything. One day it will discover the body of Jimmy Hoffa. I believe it will be found on an as yet undiscovered computing cloud.

I have generated dynamic database table in
which the colums will vary as per the selection
by the end user. Now, if my table name is car which
i have generated dynamically on the button save click
event it will have its colums like: colour, gears etc.
So can i generate a dynamic form by taking the cars id
and its column name as the textbox controls on the new
form. The new generated form will also have the basic
funtionality of add, edit,delete etc. If my table is car
then to generate dynamically car.aspx form or if table
is computer then
computer.aspx should be generated.

Changing backrow colour of a gridview based up a button click

6-Feb-09 9:47

Sounds messy to me. I'd think you want to rewrite the URL, and have a common page that gets pointed to at the end of the day.

Hi
I have been scratching my head on this for days, but getting no where!

Using visual basic and a sqldatasource for my gridview, I need change the colour of a gridview row backcolour plus set a hidden checkbox to checked when the user clicks on an image button. I also need to grab a field value from a row in the gridview.

Now, everything works when I am on the first page, but when I page to the next page I get the following error message "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".

My image buttons are connected to an onrowcommand in the gridview tag, which checks to see which image button has been called, gets the row number and then calls the appropriate method for that button.

Does anyone have a solution to set a hidden checkbox over a number of pages, grab a field value from the gridview and change the row back colour?

Thanks

If it works only on the first page, I guess you should post some code so we can look at it.

I'd never use a SQLDataSource tho, that stuff blows.

Hi
I have managed to crack the problem in so far by adding an onclick event to the image button, but if I page back the grid is refreshed and in turn the rows that have been clicked upon are changed back. Therefore, slightly modified question - how do you maintain those rows with post back?

Thanks
