C# - Fire TextChangedEvent Only When Certain Conditions Have Been Met?
Feb 24, 2011
If I have a TextChanged event wired on an asp.net textbox, it will fire everytime I add/remove a character. Is it possible to only fire it if and only if the textbox meets certain conditions such as if the textbox has a non-empty string greater than 5 characters.
I have four text boxes with start date,end, trialstartdate, trial end date. On pageload I retrieve the information from database into data table and display it on the page. It displays multiple rows. Whenever the dates(in any row) change, on TextChangedEvent I store the updated information into the datatable. After the user clicks submit I update all the information back to the database. This works fine until I change some value in the textbox and then immediately click submit button. As soon as I clicked the submit button it fires textchanged event but ignores the button click event. I have to click on submit button again to fire the button click. It works fine if i change value in the textbox and then click else where on the page and then click submit button.
Now, depending on the result of the dataitem will depend on what I want to display. For example, The databitem may show a true or false value, and depending on which one I want to show a different result on my page. So instead of it display true, it display a string. EG, if true, the text 'in stock' would display.
At the moment, I am using a method to call a function (please correct my terminology - or let me know my terminology is right!).
public string CB(object o) { //perform something return string.format(""); }
Is this the best way as it appears to be an ugly fix in my opinion. Especially as I have several items on my page which will have to use this (ususally just checking if there is a value in the dataitem or if it is empty/null)
Quick question regarding the use of Singleton lifestyle in Windsor, and Asp.Net MVC. If the following class is registered as a singleton am I correct in thinking that I will have a race condition?

I have a table that contains ID, lastname and firstname of a person. How to make my stored procedure handle the where conditions using only stored procedure.
SELECT * FROM person where lastname = @lastname
SELECT * FROM person where firstname = @firstname
SELECT * FROM person where ID = @id
Instead of making three stored procedure, I need to do it entirely in one sp.
Is it possible to have multiple conditions in an SQL select command. I have an SQL Table with the follwing filds.
Image1 Image1Approved Image2 Image2Approved Etc
Image1 is a varchar(50) and stroes the picture name. Image1Approved is a tinyint (0 = Pending, 1 = Declined & 2 = Approved) I am using the following to query the SQL database.
SelectCommand="SELECT Image1, Image1Approved, Image2, Image2Approved, Image3, Image3Approved FROM UserProfiles WHERE (UserId = @UserId)"
The part that I am stuck on is only returning the images that have there associated approved condition set. I know how to do this with a seperate select command for each image but can this be done for all image files in one statement.
I am having an Asp.net Web application in .Net 3.5 Framework, deployed on IIS 6.0. Obviously we have used Http Modules in our application. The problem is that we are having many entries specifying the message "Http Module is getting Initialized" Now, I would like to know when does an Http Module get initialized? I mean is there any specific reason? Also, is there any case of recycling of http module?
I had a checkbox in gridview to select rows for batch update, i want to disable and enable the checkbox base on some conditions.
For example, I had a column called "Status", if the status="Approved", the checkbox of this row will be disable, otherwise the checkbox is enabled to select.
I have a simple page where I am listing records from a SQL table in a GridView. All seems to work except that users could not create records. So I created a seperate page where users can add records. This is a form with fields that user fills in and click on the submit button. Code-behind VB takes care of sending the data to a SQL Stored Proc. Upon return, I am changing text of a text label on the form which display any errors that occured during the insert.
We are working on an ASP.NET CMS project using jQuery as the basis for our client side scripting. The jquery-1.2.6.js file is the only script file that is always included. Other script files are currently included depending on what components the CMS editor is using on a page or page template.A lot of the script combiners produce a static script. If we took that approach we would have to add all possible script files in just in case they were needed. We are not currently using any of the ASP.NET Ajax extensions so have not looked at what that may give us.
would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx). The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML, Divs and databound gridview content. The HTML content will be stored in the database.
the code above generates the error as I mentioned at this topic's title. I simply need to refresh my ASP.NET page, I can't use that code instead:HttpContext.Current.Response.AddHeader("Refresh","2");because it says about IIS pipeline modeThe puprose is that I must get into OnLoad method where some conditions are true after refresh/redirect
on Every page <h3> tag must come after <h2> otherwise page should be marked.
like if any page has PDF then Some particular text <p>Download Adobe reader from here</p> should be at bottom of every page is this condition is not matched then page should be marked.
I want to make different type of conditions to check then want to check on whole site and if anything mismatch then report should be generated.
We're modifying an existing ASP.NET application. We added a Terms and Conditions page with an "Accept" button that stores that choice in the user's account data. We want to prevent the user from accessing any page when the user has not accepted the Terms and Conditions.
I think we want to do this by looking up the "accepted terms" value upon login and storing it in the session. Then we need to intercept every request and check for that session value. (If it's not there, we redirect the user to the Terms and Conditions page.)
Is the PreRequestHandlerExecute method the right place to put this check? This method also gets called on requests for stylesheets and images, so it doesn't seem like it was intended for this purpose.
I've been trying to get terms and conditions (same for every page) to print on the second page of each paper. So if I have a three page document, I have 6 pages that print out. My report is as follows:
Report Header (surpressed) Page Header A - Terms & Conditions Page Header B - Header information Group Header 1 Group Header 2 Details A thru l Group Footer 1 Group Fotter 2 Page Footer A-E so basically i need a range of sales order to print say SO Numbers 1-10, each page will have detail information and on the back will be our terms and conditions. I cannot put the T&C in the Report Header because I need it to print for every group.
I have a form that has a detailsview. In that detailview I have and edit button that is visible only when a condition is met. I made the edit command field a template to achive this. My Question is can I have multiple conditions that make the edit button visible. Attached is my current linkbutton with the current variable.
I am having a staff table which contain staff information on it. To search staff information from the table, I want to prefer filter style. For example in the select query I want to display staff information according to three criterias. Select staff information from all sections, Select staff information from a given section, select staff information by a given Name. All these selects must be performed in a single select statement. Suppose,
SELECT * FROM StaffDetailsTbl WHERE SectionID = CASE WHEN @SectionFilter IS NULL THEN [SELECT ALL] ELSE SectionID = @SectionFilter and Name = CASE WHEN @NameFilter IS NULL THEN [SELECT ALL] ELSE Name Like '%@NameFilter%'
Where Declared variables are parameterized stored procedure values retrieved from the user.
