Web Forms :: Reduce The Length Of .net Generated Control ID's?
Aug 25, 2010
I'm looking for ways to reduce the size of my page . I have a page that just renders a gridview - no images - and it is over 400k!
Looking at the html that is generated I see the names of the controls in the gridview are very very long. For example: ctl00_ContentPlaceHolder1_releaseGV_ctl149_lblBuy
My gridview is about 200 rows by 13 columns = ~ 2600 spans with very long names rendered. The above example is 49 characters X 2600 controls = 127,400 characters just in control ID's!
The actual data on my page ins't anywhere near a tenth of that!
I am already storing viewstate on the server.
YES, I will put a pager on this page to bring down the number of rows. Also, I've seen sever other posts related to page size with some excellent content. I will follow up on them - however I have not seen this specific question answered.
Here is a sample of my page. As you can see there is not much data and a lot of html!
I have a label control in datalist. When thw word is long, the text of label corrupts the design. Label hasn't a multiline property.I tried different ways . I tried to use textbox like a label but this time I can't give a link to textbox.I tried to use MeasureString() method for the label. But I couldn't do it.
I have a repeater control which displays text using the following code:
[Code]....
What i am trying to do is, i want to limit the total length of text displayed to, lets say 150 characters, how and wat code can i use to achieve this task
I want label to display limited text say 20 char even the data it retrieve from database may be more than 20 char.. like in gmail,we see message body limited when we click it display whole message..how is that possible...?
I've recently added a Master Page to my site,but realized that it's caused some problems in my existing JavaScript setup.I am able to use the following code in most places without any issue to get the ClientID: '<%=myControl.ClientID%>'
The problem I have encountere is that I have several pages that add controls dynamically,and then execute events based on an ID that's passed in,where I can't use this line,because I won't know the ID of the control I'm trying to access until the Javascript executes.Here's a simplified version of the problem:
When the page runs,it creates n textboxes dynamically,and appends a relevant ID from the database to the end of the ID.Let's say the page has added 3 textboxes with the following IDs:
myTextBox1
myTextBox7
myTextBox115
Later,a javascript event fires,and I need to be able to access the control through JavaScript like this:
I am using a third party control for my web page. I do not have the source code to the DLL. I need to make a very small change the html that the control generates. Is there a way to capture the html generated by the control, and then render the control with that small change.I can override the render method of the parent control, is there a way in that method to find out the html that the control generates in there and render it with the small change?
I have a FileUpload control that currently uploads pics to the Photos folder on my server. What I would like to know is how would I give it a randomly generated filename when it gets uploaded? As I don't want duplicates later on down the line. Cheers.(Code below).
I am creating a Table Control programmatically and I want after user clicks a button to get the values.
The table has three columns, {Title(DropDownList), FName(TextBox), LName(TextBox)} and two rows.
I am getting the values for FName, LName without problem, but I am getting wrong value for Title, which is a DropDownList. It gives me for both Titles, the selected value of the second column.
More Clear
For the 1st row --> Mr, Foo, Bar for 2nd row- -> Mrs, Foo, Bar
after user clicks the button I am getting
For 1st row --> Mrs, Foo, Bar For 2nd row- -> Mrs, Foo1, Bar.
What I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control) Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />
I'm making a website that requires ads being repeated down the length of a page with dynamic length. I want the ads to be displayed down the entire length of the page, but I won't know that length until after the data has been displayed. Is there built in functionality for this in .NET? If not, does anyone see any workarounds I could employ to do this for me?
Currently, I am programming a web-based application with Visual Studio.NET 2003, and having a problem with an err below :
An error has occurred because a control with auto-generated id 'dgPreventiveMaintenanceSchedule:_ctl5:_ctl3' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events.
That err occurs while I am rendering my datagrid for certain data. In the other words, it occasionally happens.
I've been trying to debug one by one, but I still don't any clues for this kind of err.

I 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
My question is dealing with the DataList control. I am trying to add a click event to the rows of the "table" in the OnItemDataBound event.
The problem I'm having is I can't get a reference (through a row id attribute) to the "row" being generated by the DataList control (and more specifically the item template). Is there a way to add id attributes to the rows being generated by the item template?
