C# - Setting Tabindex In Dynamic Table Vertically Then Horizontally
May 7, 2010
I have a page that is currently generating dynamically created textboxes in a table format. The users are requesting that the tab order be changed from horizontal-vertical to vertical-horizontal. I know that you can use the tabindex attribute to control the tab ordering, but I can't for the life of me figure out the right way to get the sequential number properly for the textboxes. I guess this is more of a math question than anything else!
FYI, the textboxes are made while looping two different collections. First collection looped to make the rows, for each row, second collection (which is a property of the first collection objects) is looped to create the columns.
The menu control when used on the newly released VS2010 with ASP.Net version 4.0 renders vertically briefly, then renders horizontally. This causes a 1/2 second annoying flash of the menu in vertical form before it disappears and renders horizontally as intended. If you choose to render the menu as a table this problem doesn't happen, but if you choose to render the menu as a list (using <ul><li>) then if happens every time, but is hidden on development systems where response is quick enough such that the rendering vertically is not visible to the naked eye. How can I cause the rendering to be horizontal (without the brief vertical rendering)?
My web form is pretty simple. It has to have three lines of text/ASP.NET elements. The Master page has a header and a footer. I need to center those three lines in the middle of the page vertically and horizontally, especially if the bottom changes. How do I do this with CSS?
I am trying to draw a horizontal line and want to repeat an image horizontally so that it is 380px long. How do I do that? How do I also do it for a vertical line?
I have a fairly basic line graph which is bound to a SQLDataSource control. The graph displays perfectly, but I want the labels on the X-axis to display vertically rather than horizontally.
I have used the following code to try and do this but it is having no effect:
I have an ASP.NET Webforms site that is regularly having features added.The majority of time a new WebControl is added to the page and I need to increment the TabIndex to all subsequent controls on the page.I'd prefer a more robust solution than choosing an arbitrary gap between the initial assigned tab indexes. Setting the tab indexes using the designer tab order functionality is one option but I'd prefer to stay in the source view.Ideally, if I had, for example, three check boxes I'd like to be able to define the tabindex based off the previous controls tabindex. Then I'd only need to insert the new control and change one existing control.For example, add a new property TabIndexAfterControlId to WebControl:
Just posting this up as I've been searching all over the net for the last few hours and not found anything useful. What I need to do is set the tabindex on a content page so that when using keyboard navigation the form controls in one vertical column are selected first, and then the 2nd column. (rather than one row at a time).
My problem is this means that the "skip to content" and all the other links in the master page are bypassed and the first form control with a tabindex!=0 is jumped to. Is there any way to set the tabindex on a content page relative to the previous tabindex from the masterpage? (when no tabindex is set on the master page).
I was hoping at the top of the content page you could set relativetabindex or something like. we use many different masterpages that change fairly frequently so setting the tab index for every control on the page is a really horrible way to get round this. I'm hoping theres a nice .Net way of doing it and no javascript hacking has to be done!
I'm working on a ASP.Net web page with two tables positioned in the center of the page with one on top of the other. The table on top contains input fields that are dynamically generated by the code-behind, so the number of input fields varies. The table on the bottom contains content that is constant and doesn't change. The layout of the page is fixed and must remain so. My question is, how do I make the bottom table dynamically adjust vertically so that it doesn't overlap with the fields from the top table. The general HTML layout of the page is something like the following:
[code]...
I'm thinking I could wrap the bottom table in a div, but I'm not sure what specific styling will achieve the desired effect. I basically want to maintain the fixed positioning horizontally, but have the vertical alignment adjust to prevent overlap with the top.
UPDATE:
Here is a screen cap that shows the two tables overlapping. The buttons you see are in the bottom table, the fields are supposed to be on the top, all elements are positioned absolutely in the center of the browser screen.
UPDATE 2:
I updated the HTML sample above with the styles that are currently in use.
I have a dynamic Table which contain 8 rows and 8 Colums
Table t = new Table(); TableRow rr = new TableRow(); TableCell cc = new TableCell(); and in the each Cell CC I add a dynamic Button(Or Linkbtn) LinkButton LB1 = new LinkButton(); LB1.Text = "AM"; LB1.ID ="Link1"; cc.Controls.Add(LB1); rr.Cells.Add(cc); LB1.Click += new EventHandler(LB1_Click); t.Rows.Add(rr);
i have a table with 8 rows , 8 colums and each cell contain a LinkButton (which diffrent in IDs) I want to add Lable in the same cell of this LinkBtn(LB1) which it clicked but I cann't What shoud I write here?
There is a small advancement in my app, developing using ASP.Net and C# on fx4.0. Requirement is that my client needs dynamic paging size. He wants to set page size of all gridviews approx 10-15 , as needed. If he wants 5 then my app will display 5 and if he sets 10 then the app will display 10.
I'm guessing this is actually an impossible task, but I thought I'd run it by StackOverflow to see if I'm wrong. Basically we have some dynamically created URLs for SEO purposes (around 300,000+ of them) and we want to do 301 redirects to them.
Google still has a load of the old URLs indexed, but we obviously want them to know that they should be replaced with our newer ones (and that it's not just duplicate content), hence the 301 redirects.
Our problem is that the <Brand> and <Product Name> parts of the new URLs are obviously dynamically created... making it impossible to create 301 redirects for them.
I am trying to generate a dynamic table andd add rows to a ASP.Net table control on my UI. My problem is as I add a new row from MyTable, in to another table the table I am copying from, will loose one row. Here is the code:
Table myTable = new Table ();
[Code]....
am just reading one row in every loop and add that row in to another table object, why is 'myTable' loosing loosing one row in each loop?
So my dropdown will be populated with a list of years that could be different depending on the SchoolID passed in. I want my default value to be the max returned in the SELECT query minus 5 (so in other words, the max index minus 5). For example, if my list of years was:
i have a page where i have a search area for users and a blank table. When a user performs a searcg,im creating in the cs the rows for the table and adding in the cells textboxes with values from DB. The textboxes ID´s are also being retrieved from the DB. Then, the user can change values from the textboxes. I also have an asp button that´s supposed to save the changes BUT i cant manage to persist the ids and last values between postback. Ive tried something ClientScript.RegisterArrayDeclaration but the array comes up empty. Then i used a hiddenfield but does the same trick.
what am i doing wrong?I add the hiddenfield,i try to add all the controls ids to an array but seems impossible,and there is no way i am getting the last values in another array. Im loosing everything between postbacks, but if i manage to save these ids and values, ill re-make the table in a sec.
I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet.
I'm wanting to adjust this code to pull the theme name from a database table, instead of just manually assigning a theme in the file. This way a site administrator can set the theme dynamically. If never done this with a global.asax file, so I'm not sure what the best way is to accomplish it?
Here's the code that needs tweaked:
[Code]....
The database table could be "ThemeName" with rows ID & Theme. If performing this in the global.asax file will cause any big performance issues.
I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.
I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).
I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:
