Hi
I have a Web User Control (ascx) that sits on my Master Page. It displays a summary of what's in the user's shopping cart. I want the ascx's summary to update as soon as the current page makes a change to the shopping cart. I noticed that the ascx wasn't updating until the next page load after the one that updates the cart, because the code I wrote to display the summary was in the .ascx's OnLoad, and this fires BEFORE the Page's OnLoad (where there is code to update the cart). So I put the .ascx summary code in it's OnPreRender and now it updates as I want it to, because the ascx's OnPreRender fires after the Page's OnLoad.

Although this works it seems like a bit of a hack. Is this the correct way to update the ascx's contents, or is there some other better way of doing it?

I don't know if this is the best approach, but have your tried loading the control at runtime??

Replace the control on your website with a container (a panel for example) and let's assume you name the panel pnlCartContent.

<br />
Control ctrlCartContent = null;<br />
<br />
try<br />
{<br />
    ctrlCartContent = LoadControl("relative/path/to/control.ascx");<br />
    pnlCartContent.Controls.Add(ctrlCartContent);<br />
}<br />
catch (Exception ex)<br />
{<br />
    response.write("Damn, those exceptions!<br>"+ex.Message);<br />
}<br />

Have fun!

Thanks for your reply Eduard.

This would seem to work too, but still feels like a little bit of a hack. I'll just use OnPreRender for now.

Cheers!

Have you considered opening a bitmap object from the URL??

<br />
string sDrivePath = Server.MapPath("relative/image/url.jpg");<br />
Bitmap bmpYourImage = null;<br />
if (File.Exists(sDrivePath))<br />
    bmpYourImage = new Bitmap(sDrivePath);<br />

You can then create a new Image object from the Bitmap object, sounds good to me Cool | :cool:

Tnx, sounds like a great Idea, but my URL is longer than 260 chars and I therefore get a System.IO.PathTooLongException. I have no way to pysically shorten the URL, because it is from a web resource...

Problem solved.
I used Keilholz approach and solved the URL length exception by creating the image based on inputstream (With the URL as source). I were then able to store the image locally on the web server.

Thank you for your help!

This will add the template column in datagrid
Dim tempcol As New TemplateColumn
tempcol.HeaderText = "Runtime Display"
DataGrid1.Columns.AddAt(2, tempcol)

second in itemcreated event write
Dim lbl As New Label
lbl.Text = "Testing"
e.Item.Cells(2).Controls.Add(lbl)

and last use editcommand to add dropdownlist
e.Item.Cells(2).Controls.Add(New DropDownList)

i hope this will work

You can either choose to store them in your web.config file, or to store them in a seperate data source, where a datasource can be a database, an excel sheet or even a plain text file. It's all up to your imagination...

Can I write multiple delete statements for the delete button click in the gridview?

Normally gridview facilitates us to give a single deletecommand for deleting the record. If the record has to be deleted from various tables, what can be done. Please advise.
