Now i have a checkbox column in the gridview, and select all checkbox also, for functionality of checkboxes i am using javascript like what is explained by this article: [URL] ....
I like this way its simple and fast. but now when gridview refreshes the checkbox selection and others styles disappears.
Now what can i do to keep my selection as it is on gridview refresh. Do i have to stop the gridview refresh on checkbox selection?
I have a datagrid which retrieves particular columns from an SQL database table. I also have a checkbox appended on to each row, so that selections can be made against rows of the users choice (i.e. select photos to add to favorites).
How can I code this (in VB.NET) so that these checkboxes are processed sequentially? I have heard an "array" might be best for this, but don't know how to code it. Essentially, I want the VB.NET to look through the datagrid list and to process only those rows with checkboxes checked, by applying some SQL based on these selections.
I want to create a page on which the website's sponsors are displayed. The information about the sponsors is coming from the database via an ObjectDataSource, and I'm retrieving an Image (company logo), the name of the company, and a url to the company's website. Each Image (logo) is of the same height, but of varying width. I want each Item to be formatted so that the Image is on top, and underneath is a centered hyperlink with the name of the company.
This all seems pretty straightforward ... now for my problem: I want to display as many of these on the page as possible. Essentially, start off horizontally and fit as many as possible on each row. A DataList or Repeater with RepeatDirection=Horizontal doesn't quite do what I want as I don't want to have a fixed number of columns.
Is there an easy way to achieve this, or do I have to manually add up the width of each item on an ItemDataBound event, and then somehow move to the next row when the maximum width is reached? In addition I have to deal with the fact that the width of my Item is the maximum of the Image width and the text underneath.
I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn 1 1111 2222 3333 Yes / No (selected Yes) 2 2222 3333 4444 Yes / No
I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.
I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?

How to filter Max or min value from gridview data which is bind with sql datasource.
Like I give date range from and to all the data popup in gridview then I have dropdown with 2 values Max and Min. If i select max so max value from payment column gridview shows and if I select min so min values from payment column shows.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
I get the following error from a 550 line sql statement with multiple temp tables:
"The maximum number of tables in a query (260) was exceeded."
Are there any tricks for getting rid of this error? The long query is required for this program. Will I need to build a new table before the query runs?
I've got a sql table, that just keeps getting more and more columns added. I optimize the db as much as possible, but am curious about how many fields a table can have, and if there is a way to check if I'm getting too much data per row?
My ASP.NET MVC 2.0 web application does not maintain any session state and My production machine has n (>1) core, .NET 4.0, IIS 7.5 Integrated mode.For increased performance, I am curious if I should increase the max concurrent threads in thread pool to 12*n or should I keep the max concurrent threads as 12 but assign n worker process (w3wp.exe) to my application pool. What are the pros and cons of one over another?
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same error. i even deleted the files in this folder
(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error. i found a article on msdn that states that its a source code issue. Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error:
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
