I want to set the coulms size of all the columns in the table in the DB based on the maximum width/size of one of those columns of that particular table That is if I have three columns Name(nvarchar 50), Address(nvarchar 70) and Description(nvarchar 100), then I want Name and Address to also be nvarchar 100, can anyone give me the code for the same in VB.
View 1 RepliesI've already searched to no avail for an answer to this question:is it possible to dynamically alter the page size in a paged gridview based on data in a particular column?In other words,let's say I get data from a table that lists students enrolled in a particular course.If there are 10 students in Course "A," then I want page 1 in my gridview to show 10 records.
If there are 15 students in Course "B," then I want page 2 in my gridview to show those 15 records,and so on.I imagine that this could probably be done with a master-detail kind of set up,but let's say for the sake of argument that I don't want to go that route.
I am using PageMethods to send a few parameters to a webmethod in my codebehind. The method runs a stored procedure and uses the results to build a string that I am returning from the method.
Everything works fine until I try to include too many records in my results..
Once the results I am trying to return hit about 70K, the pagemethod times out even though it is taking about 1 second to process the results.
Is there a buffer limit or limit on the size or results returned from a pagemethod and if so, where can this be set or changed?
Is there a setting in the web.config somewhere to handle pagemethod buffer size?
I know the content palcehlder does not have a size ,I have a masterpage and content page, the master page has a table with a header, content area, and footer, header and footer are fixed size, content area is 100%. As the user sizes the browser the content area grows and shrinks and the footer stays at the
bottom of the browser window - perfect!
Problem: The contentpalceholder does not grow to fill the available content area. Now, the contentplaceholder gets its size from its contents, which in this case is a div holding a silverlight object.I was thinking I could hook the master or child page's re-size event and somehow pass that info onto the SL object, but as it turns out (and I'm surprised I never knew this) there is no aps.net page re-size event! (really?, wow.)
So is there a way to get a SL object hosted on a master page to size itself based on the size of the browser window?Or more generally, a way to size the contents (like a div or panel) of a contentplaceholder based on the browser? on a standard aspx page (not a master page) I CAN get the SL object to size itself based on the broswer, the problem seems to come from the fact that I'm hosting the SL object in a content placeholder.
I guess I could 'unroll' the master page into several standalone pages and have it work, but the menu is on the master page and I'm used to using them, plus it's already done...<sigh>
I am exporting a HTML table to excel by sending the data as a HTML Table string and setting the content headers:

i have this column in a datagridview on aspx page

I'm going to design a database for an image gallery in ASP.NET Web App . Because of some reasons I've decided to store the image in Data Base , Not the address .
In the application i need two or more different size and weight image for each image that the admin insert .For instance , One of them is small and lightweight thumbnail , and the other is Original big one .
My question is : Should i have two column ( one for lightweight and small thumbnail and one for big and full size one ) in DataBase Or Is there any way i could load different size and wight image from Big and original image column ?

I am using TabContainer with some controls on each tab (asp: labels, text boxes). When redirecting to the page that contains the TabContainer, the tabs and their content loads as expected, but when there is a postback, and the page refreshes, the TabContainer UI changes - the font size of the labels gets bigger, the text boxes become bigger and their location changes a bit (not aligned as before), and the tab header is partially hidden. I am using IE7.
I dont know if this is relevant but in some of the text boxes i use edit mask extender as well for date. Also, I have used a table inside the TabContainer for layouting the controls.
In login.aspx I have used login control to enter user name and password, the problem is: even my caps lock is off when I enter user name it prints in capital letters but size is small size (when I copy and paste in note pad or msword it paste in small letters not in capital letters), when I turn on my caps lock on and type - it prints in bigger size as if I am typing in capital letters.
ex: 1. temp is my user name if my caps lock is off it shows like this TEMP (but size in smaller than 2nd one)
2. if my caps lock is on is shows like this as if I am typing capital letters TEMP
what do you think the problem is how can I fix it
As I know, by default Cache is stored in the memory and to the disk at the same time DiskCacheable=true).When the cached response is removed from the output cache due to memory pressure, it still remains on disk allowing a much larger set of pages to be cached. In addition, disk cached pages survive application restarts. And this is already in ASP.NET 2.0.I dont't know in which order the caches are removed from the memory and readen from disk instead? I would like to achive, that caches with the minimal trafic, or the longest last used, would be removed first from the memory. Is there some settings to do that, or even by default works that way?
View 1 RepliesHere's the scenario:I have an asp.net webpage which displays dynamic data in a gridview.I'm using a master page to display the header and footer of the page, and this gridview is being displayed inside a div in the contentplaceholder.
The Problem:What I want is that the size of the page that is displayed remains constant for a user and must be equal to the size of their browser's available display area and the content being visible by scrolling the div.Sort of like the header and footer remain at the same position and the content inside it is scrollable.
according to the developer of the web service I am calling.He said "bump up the default values for the following":
maxBufferSize="4096000"
maxReceivedMessageSize="4096000"
Where can I put these to bump them up? I've tried googling these settings, and I get sections of web.config that I don't have. I don't have a WCF client, either. Does this make sense to do from my web service, developed in VS 2010?
I'd like to just call his service without changing anything, get the error, and then go from there. I'm even getting that far because I got some other exception saying server was unable to process request, but it had nothing to do with exceeding a buffer size.
I am using item template and eval function in the gridview to display the records. Can I add a coulmn which is not in the table?
I have to add some columns which is not in the table and assign the values from code behind to that particular column
I added a DateTime column to a table in my database through the Server Explorer. Because the team lead for this project wasn't savvy on nullable types, one of the requirements was that there be no null values in the database. This requires me to program all sorts of useless code into the system, but that's another story. My problem arises when assigning a default value to this column. I typed the following into the cell for the "Default Value or Binding":
1/1/1753 12:00:00 AM
When I went to inspect the content of the table, I found that all of the dates had been populated with:
1/1/1900 12:00:00 AM
I have a gridview which displays following columns:
TaskID, TaskDescription, IsComplete, DateOfCompletion
Now what I want to achieve is, when user clicks IsComplete checkbox, she must enter the date of completion. So, I want a validation (client side) on DateOfCompletion if the checkbox is selected (checked). And, I also want to use Validator Callout Extender
if possible.
How can I achieve this?
So I have an <asp:Gridview> and in my C# file, I am setting the datasource to some database table, and doing .DataBind().
However, I want to hide a column in the table based on a Boolean variable.
Something like this:
gridview.Columns['Field5'].Visible = false;
Or perhaps:
int c = gridview.Rows.Count();
for(int i = 0; i < c; i++){
gridview.Rows['Field5'].Remove();
}
Perhaps I cannot make it invisible, but I'm sure I can at least loop through and remove all rows related to the column "field5". I don't know how to go about doing this.
Does anyone perhaps have a proper link to using the GridView Class and how all the methods are suppose to be used because it's not clear, perhaps not written by microsoft?
the internet seems to lack a lot of C# documentation (or maybe it's just cluttered with too much useless ASP.net information).
can you set the the image size of this control with css?
<img style="border-width: 0px;" alt="Test image" src="userdata/1/uploadedimage/database%20entry.jpg">
Not sure if theres a way I can assign a certain size to this either by css or by Jquery? Or if I can do it directly in my C# code using something like img.Style?
EDIT:
Just to clarify my css is like so:
div .test
{
width:90%;
z-index:1;
padding:27.5px;
border-top: thin solid #736F6E;
[Code]....
So how would I use the below answers in this combination
I have a DropDownList being filled from a data base. Now, when I select the drop down arrow, is there a way to set the size of how many lines to show initially ?
Like: DropDownList2.Attributes.Add("Size", "16")
I cannot find an event when clicking the drop down arrow.
I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:
I have read many pages on detecting mobile phones but my question is for setting the screen size for this. I can easily made the screen the same size as my mobile phone but on some devices you still have to zoom in to see it. Is this mainly on the device side that needs to be set? Is there any way to tell the device to show the page zoomed in?
