I have two user controls both have a repeater and a button. They are both on a .aspx page. I need to capture the values from those two buttons on the user controls in variables on the .aspx page. Right now, I have two labels on the page that I am outputting the values of the buttons to, but they don't have a value right now, which is my problem.

I have 2 columns (name and address) in a gridview which are defined as linked buttons. Now when i click on a record in the first row (name) i am able to pass that value (selected name) to another page with rowcommand. Now i am trying to click on the second row (address) on a record but am not able to pass that value to the second page. Don't actually know how to define this in the code below. The first row (name) has to redirect to one page (this what i have already accomplished) and the second row (address) has to redirect to another page

I am looking to cache a dataset and then filter the results as they will be used repeatedly. However, I don't know how to assign values in the filtered dataset to variables in C#. I have looked on the internet for the past few hours but all I can get in binding the dataset to a control.

I am looking to retrieve data from a database and assign those values to class objects which in turn will be turned into session variables. I am using an object datasource to retrieve the data from the database but I cannot find anywhere that shows how to assign these values to variables. The data is returned in a dataset. There is the added problem that there will be mulitple items returned which will have to be assigned to different arraylists of objects based on the a primary key in the database.
View 4 Replieswhats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
I am writing what i will call a survey system. The surveys will consist of a series of questions, split into sections. The survey definitions will be stored in a database. The questions can be of various types, that have different input methods and validation (e.g.textbox, numeric textbox, selectlist etc.) I am creating a set of user controls that map to different question types. I would like to completely abstract the survey rendering logic from the, survey definition logic. The way i thought i would do this is to use a dumb rendering control that simply takes a collection of controls and renders them out in a for each loop a super simplified version of what I am doing.
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(CurrentControl)
}
}
This works in the sense that the correct controls get added to the place holder,however nothing renders. Presumably this is because it does not have the markup in the asxc file.
If i do something like this
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(this.LoadControl("path to ascx file")
}
}
It will create the correct number of controls, but i don't want to instantiate the controls here because i would need to to set various properties based on cconditional logic i want to abstract away from this pure rendering layer.
what i want to do is instantiate the controls else where, set the relevant properties and then simply pass a collection of these into the rendering control to render out.
Is there a way to do this with user controls? Would i have to create custom controls instead?
I am a complete noob to ASP.NET (C# based) and have migrated from PHP (I have mentioned this a few times but I feel I have to 'cos some of the questions I ask seem so basic!)
I have page (Products.aspx) it has a grid view using products from the northwind DB, the grid view is paged to show 'n' products at a time and has an extra column which is basically a 'view this product' hyper link, the user can click on this link and is taken to another page (Product.aspx) which provides complete details for that particular product, so, this is what I want to do next, I want to add a button that takes the product ID, (or other unique property of the product - it doesnt really matter at the moment, but i am likely to stick to ID).
Then take that value and place it in a cookie, (I know that session variables are held in cookies, that is not really a problem at the moment, I am concentrating on basics, then I will go a little more advanced).
so, I have a button - call it productIdBtn, and its value, which is going to be the product ID, in the button on click handler, how would I add this value to a cookie - call it prodIdCookie?

I have a detailsview with template fields. when i go into edit mode i am trying to set the selectedvalue of a dropdownlist to be the value of the corresponding label from the item template in code behind as once i go into edit mode i loose the initial value from the detailsview and the dropdownlist defaults to the first listitem. what i am doing is onDataBinding of the detailsview i access the cell value of the label , i then assign that to a public variable but once i've exited the routine the public variable looses the value of the detailsview cell i've just assigned to it. this is the value i'm hoping to assign to the selectedvalue of the dropdownlist when i go into editmode. The reason i'm doing it this way is although i can use bind in the html to mantain the dropdownlist selected value between detailsview states once i come to update the detailview i get the following error
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.to work arround this i've had to assign the values to update paramteres also in code behind. here's my code behind page i've bolded the routines in question. drpDataStoreDDL is the variable in question.

I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:

I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
Requirements call for the ability to save search values so that they can select them at later times to return the results without having to re-enter the values. They have the ability to search on 4 different types of data (Date, Time and Lat/Long), so they would like to capture what was entered and ONLY if they chose to save those values, it will be saved and next time they login, if they are searching, they can pick an old search and submit it again.
Im thinking that i add a checkbox next to each button, if they check it, it saves the data into a table with there values and username. Next time they login and go tothe search page, if there are any records for them in the table, i present them with a link that displays all the values stored and if they select one, it will run the search again and present them with the results. does that sound like the right way to handle this request?
I am binding the ReorderList in my code behind file. I am not using a DataSource Control like SQLDataSource etc. How will I capture the values edited, in my ReorderList1_UpdateCommand(). In GridView we can use something like

I have a situation where I need to generate multiple sets of radio buttons. These radio buttons display One to Many relationship data.
I know how to get it to work with a workaround that I used back in Classic ASP days ... in which I essentially just spit out the HTML dynamically and keep track of my controls using systematic IDs. Which is nothing more then an Primary Key appended to a string constant i.e. String.Format("Dynamic_{0}", myChildRecordPKValue) so my HTML looks like this:

Note that I am using a javascript function which updates a hidden field with the selected value (Each parent record has a corresponding hidden field). So after making selection user will hit the submit button and I get my values using Request.Form[myHiddenField1] and so on ...
For some reason it seems as though variables that I declare in javascript sometimes persist themselves across applications even when I do a response.redirect. I thought that a response.redirect would clear them out.

I've got some ASP pages where the session variable values get blown away BEFORE the session times out. I can't understand it. For example: if a user logs into my ASP app using his password which is stored in a session variable, it will be fully accessible for a few minutes and then all of a sudden.....Wham session variable with password value is gone. And the session timeout is far from expired. The session variable is not being touched in any way after it gets initialized with a value.

View 3 RepliesI have several pages linked together that I want to maintain drop down selections for. I've seen a number of ways to do this with session values, etc, but I want to set the default value while still having the option of selecting other values.
Effectively, users will make selections on page 1 and then on page 2 they will use those same selections, but also potentially want to change their selections. My thought was that I could load the selections into a table in SQL in page 1 and then in page 2 call that table and set the values as variables. My question, then, is how I would set the default dropdown value to be a variable as opposed to a set value.

1.Users === Drop Down Menu then in the Drop down should be the names of all Taafoo staff.
On one of the pages, there is a need for me to add a textbox in which the user types in text. It is important for us to capture what the user is thinking while he's typing in the text, so strokes such as backspace, keys should be captured. Once the user clicks on the submit button, the administrator should be able to 'play' the actions and review how the user progressed while he was typing in the text (similar to watching a video)
Is there any ASP.NET custom control that would have this capability?
