C# - Selecting And Building A Control From A Control Library Dynamically, Using The Control Name From A Table?
Feb 1, 2010I have a custom DDL that lives in my Server control library. Currently I add this control to a table by strongly typing the name of the control, the customary way.
Control_Library.Report_NumberDDL newDDL = new Control_Library.Report_NumberDDL();
What I want to be able to do is dynamically create that control by pulling the control name from a table. So I would have the name of the control in my code, in this case "Report_NumberDDL", and I would like to then create the control without having to strongly type it.
Something like this, though I know this doesn't work:
string controlName = "Report_NumberDDL";
Control_Library."controlName" controlNum1 = new Control_Library."controlName"();
Edit:I tried to do this:
Type type = Type.GetType("Control_Library.Report_NumberDDL");
object control = Activator.CreateInstance(type);
But on the CreateInstance(type) I get a null value exception. So the Type isn't getting created correctly.

Forms Data Controls :: Programmatically Creating Chart Control And Adding It To Dynamically Generated Table?
May 21, 2010I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

Web Forms :: Dynamically Created Table / The Table Subsequently Disappears?
Mar 9, 2011Im creating a table dynamically in my codebehind to display some statistics. The table is in a usercontrol. When the page first loads, its created and displayed correctly. If I do something that generates a postback, the table subsequently disappears, this is because its created inside a !IsPostback. How can i ensure that the table, once its been generated, stays visble on the page ? I dont want to generate it each time the page loads as it involves a lot of calculations on the database which will slow the pageload down.

Web Forms :: Dynamically Created Table Will Not Appear After Postback?

I think it will be a typically beginner error, but I wasn't be able to locate the error whereas reading different posts and tutorials related to this topic.

Web Forms :: How To Dynamically Create And Populate HTML Table
Dec 10, 2010I've created a static table, which looks just as I would expect it to, but I want to reduce my work in the future, as I'll need to create more rows and columns to store extra data that's added to my application.
So rather than creating new rows and columns whenever I need to, I'd like to automate the task by pulling the data from the database and populating a table that's dynamically created based on how much data is pulled.
e.g. if there are 10 rows of items in the database, create 10 columns and 10 rows, if a further 5 things get added next week, I want to add another 5 rows and 5 columns etc
Is this where "Dynamic Data" would play a role? If so, it's completely new to me, my needs are just for a single table on a page, not something that needs to be done en'masse all over the website, if that makes a difference?
Web Forms :: Get The Backcolor Of Dynamically Created Table Cell?
Oct 19, 2010I am unable to reterive dynamically created table cells back color which has been changed by the click event of the cell.I am adding table cells dynamically on asp.net page and also setting cells back color. So when the page is loaded, table has number of cells with different colors.Table cells back color can be changed by clicking on it through java script. On page post back event, i am jutst getting those colors which were set before the click event.For example:When the page is loaded, cell1= red and cell2=red.If i click on cell2 then it will change to blue so now cell1= red and cell2 = bluebut on post back i am getting cell1= red and cell2 = red.Table is recreated on post back event.
View 3 RepliesForms Data Controls :: Dynamically Adding Rows To A Table
Apr 19, 2010I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
Web Forms :: Dynamically Created Table - Empty On First Page Load
Mar 10, 2011I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?

Web Forms :: Dynamically Adding Controls To A Table Across Multiple Functions?
Mar 13, 2010I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.
When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.
In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.
I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?
