ASP.NET - TargetInvocationException - ASP.NET Discussion Boards

This would work but if every image is 200kb and on every request it stores a copy on hard disc then the hard disc would run out of space. from my toying around with it if in my event code changes the image to another image on the server that works fine however, same image is really a pain. I tried several cache cleaning methods i found on Google but they don't seem to solve the problem.

Yeah, you obviously need to delete your old image when the new image is requested, or have enough HDD space to store them all.

Hi Dear
I use VS2005 (ASP.NET 2) & SQL Server 2005
In a Gridview i have a column that is a foreign key & it's data type is TinyInt. I want to show another data field that is related with master table, like a ComboBox that has 3 parameters (DisplayMember , ValueMember & SelectedValue), but there isn't any SelectedValue paramete in my Gridview !
How can i do that ?

You have to find the combo box in the row that is selected and then get it's selected value. The combo box, not the grid view row, contains the value.

Hi, set your gridview with a datakeys.

Datakeys one of the property of your gridview.

datakeys = [columnfield from database]

Hi,
I have two tables LaptopBrandsTable and LaptopModels table. In my asp.net page, i have a searchtxtbox.
I want to generate a page , that shows all models for a particular brand in a page, which when clicked shows details for the laptop. I might have 100s of laptop under one brand so if the entries become more than 35, i want to start another column in the page. Which asp.net control would help me do this, and how would i make the models appear as links..
eg when searched for acer, i want to show

acer aspire 1 acer aspire 36 acer aspire 71
acer aspire 2 acer aspire 37
.......... ........
acer aspire 35 acer aspire 70

Thanx..

best regards,
mark

Use a repeater to generate your links, and then just form URLs that pass an id to your final page to read the details from the DB

Did you google the error ? Work out what page is causing the error ? Is it just one page ? Do you know what line of code does it ?

It's noted that controls are crammed up when running the webpage even though they seem to be aligned within the IDE.

NEVER use the designer, it is CRAP. Write CSS, use tables or just use br tags to space stuff out on your page.

Thanks, would you suggest another IDE that might work better? Have you glimpsed at VS2010 by any chance?

how to pass array from one page to another?

First of all what is the reason for passing the Array over page? If its same for all user try to store it in Application Variable or For different for every user use Session.
But why you are trying to do that ?

You've asked this a few times now. Is it homework or paid work that you're taking on, but have nothing close to the skills needed to do ? If it's homework, talk to your teacher. If it's paid work, tell the client you are a fraud. If you really want to do this, just read all the answers you got last time, and if you post again, post something like 'I was told to do xx, here is my code, and here is where I am still stuck'. The alternative, is to decide that programming is beyond you and to do something else with your time.

if you know u help but pls dont try to degrade one's ability because one or other day u ll also in d situation to get help from others...

you're wrong. I have far more difficult problems than yours and I solve them myself, with google and with textbooks. I DO ask questions from time to time, but never as basic as this one, and never without reading and applying the answers.

Hi, you must have public property for your array.

example:

private _id as string()

public property strID() as string

Gosh - that's more clueless than even the OP. This thread is getting better all the time.

How does he pass the property between web pages according to your answer ?

I have a listbox and MovetoTopbutton,MovetoBottombutton

when i select an item in the listbox and if i click on MovetoTopbutton
then the selected item should be placed in top of the listbox

vise versa for MovetoBottombutton

how to do this one.................

Someone else asked this a couple of posts down ( or you asked twice with two different accounts) . It's done with javascript, which means it's not really an ASP.NET question. Google for samples
