C# - Update The DOM But Do A Check On The Data With The Code-behind?
Feb 23, 2011
This is with ASP.NET Web Forms .NET 2.0 - I have a situation that I am not sure how to fulfill all the requirements. I need to update an img source on the page if selections are made from a drop down on the same page. Basically, the drop downs are 'options' for the item. If a selection is made (i.e. color: red) then I would update the img for the product to something like (productID_red.jpeg) IF one exists. The problem is I don't want to do post backs and refresh the page every time a selection is made - especially if I do a check to see if the image exists before I swap out the img src for that product and the file doesn't exist so I just refreshed the entire page for nothing.QUESTION:So I have easily thrown some javascript together that formulates a string of the image file name based on the options selected. My question is, what options do I have to do the following:submit the constructed image name (i.e. productID_red_large.jpg) to some where that will verify the file exists either in C# or if it is even possible in the javascript. I also have to check for different possible file types (i.e. .png, .jpg...etc.).not do a post back and refresh the entire page

I have a detail view, i can edit the detail view but cannot update. i do it at code behind, no data source was use. because i need to update multiple table at the same time when i click update on the detail view.
What I am looking to do is when I run the srcipt, I want to check to see if this has been run or not. If it hasn't been run then I would like it to update the record, if it has been run then I don't want it to update.
I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.
i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.
I have a check box in the grid.IF IsChecked has a value checkbox should be checked else not.Should i check the check box in the ItemDataBound event or will it get checked automatically.

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
I've come to a roadblock in my app and I'm not sure which way I should go. Currently, I have a slider control and two text boxes used to set the Start and End times of a section of a video. Let's say the video is of some Music Awards. In my database, I've tagged the start and end time of each celebrities on-screen appearance. When the user adjusts their start and end times on the page, I want to query the database table and pull back all celebrities within that range. The problem is I don't know how to do this in JS.
Can I use the Check Box List and bind the values to it? Do I need to render a table of Check Boxes in JavaScript? Do I call the Server-Side code via Ajax and then partially render the page?
