Web Forms :: Create And Add Dynamic LinkButton From Database?
Dec 23, 2015
I have a question regarding in Creation of LinkButton from CodeBehind. I have table which is consist of 4 records. And that 4 records will be created as LinkButton. Here is the hardcoded HTML and I want to convert it to Dynamic
I have a query give me two column and several rows say 20.
The first column i want to bind with dropdown list and second to textbox.
i would like to dynamically create dropdown list as well as textbox as i do not know how many rows i will get it every time.
My select query is like this -
"select subcatid,categoryname from category where catid=10"
That give me say 12 rows with two columns,i want to select the subcatid and bind it with dropdown list and categoryname to textbox that can be edited by user.
Problem : I have Added One Link button to the above Table.. Click Event for That Link Button Is not Firing Now. when i click on link button of table event is not firing at all.
I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.
And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event
Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....
The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this: Grivdivew ItemTemplate PlaceHolder[code]....
So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:
On the code behind, I am setting a variable called test and on Page_Load, changing the variable to something else. How come, when I click the dynamically added LinkButton, the test variable is not maintaining it's state:
I have a series of linkbuttons that are generated dynamically inside a repeater.
I need the background color of the selected linkButton to change and remain a new color when clicked. I thought that the ItemCommand property of the repeater would do the trick, but it doesn't.
im creating dynamic buttons on page load and on the click event of button1 handlere iam creating more buttons this is going fine but on click event of button 2 work is not done so how to maintain a chain of creation of button on click events
I want to grab a numeric value from the database and thereby use it in a datagrid. This will be connected to a linkbutton which has a hyperlink which will bring up profile information based on the number returned. I'm getting a value back but when I click the link, the querystring sees <% instead of the id number I want to use. So I'm really not sure what I'm missing so here's my code:
I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?
I know how to create a dynamic ddl. but I can't keep it! It want to have 1 ddl and after selection create another one and with selection ofthe second, third is created and so on. I can create second ddl and addhandler. but when I change the second ddl it disappears!
