Custom Server Controls :: Paging And Sorting Gridview Custom Control Inside Of A Wizard Control?
Dec 24, 2010
here's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
//create new step
//added custom control to new step
//add step to wizard
//added wizard to a placeholder on a page
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.
Moderators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction 2. I can have the custom pager like
<<Previous 1 2 3 .. 7 Next >>.
When i click the next when i am viewing the page at 3 , the pager links should change as
<<Previous 2 3 4 .. 7 Next >>
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.
I have used calender web user control inside my project where i took textbox,button and calender...but after dragging onto my aspx page..i am unable to access this textbox,calender and button on aspx page..
I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.
created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen has entered a date?first custom control I have created and have been using google.
I have created a user control and am ready to convert it into a custom control. I am trying to follow:
[URL] the steps mentioned in the link.
I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.
I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.
I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?
I have 3 pages in each page there is a portion of page where it is common in all these three pages.Thought of making the common stuff as a separate control either User control/Custom control.Any suggestions on which one should i use custom/user control
i am new to technology so go easy on this post according to what i read from web there are 3 type of custom server controls 1 superclass2 composite 3 renderedi found video tutorial for superclass custom server control but couldnt find video tutials for other 2.lease forward me link for composite and rendered custom server controls video tutorial
I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
I have created a really simple custom control to render panels into a page. The code is below. When I use my control and add any webcontrol to it, after each page postback the contents of these child controls vanishes.
I must have missed something really simple but run the example to reproduce this. Can anyone please enlighten me as to why the controls are being 'emptied' of their contents, and how I stop this occuring?
