View 2 RepliesI'd like to create a user control which takes XML as input, applies an XSL transform on it, and displays the results of the transform in the web form or windows form in place of the user control. The transform should happen automagically when the windows form or web form is first loaded. I'd think this would be pretty easy to do. I just don't know how. point to a guide/tutorial on how to do this?

I know that how to create custom control and add custom property.
I want to create property like DataSource to my custom control.
I want to create a custom control where I define several specifically named DIV sections. The code-behind logic of the custom control will perform operations on these named DIV sections. The page where the custom control is hosted needs to be able to add named controls to the DIV sections and perform operations on these named controls added to the DIV sections.
Let me explain a little further. In the custom control, I want to have code behind logic that fires the following Page Event and uses a condition to make one or another specifically named DIV section visible or not:
< _
ToolboxData("<{0}:BaseDetails runat=""server""></{0}:BaseDetails>") _
> _
Public Class BaseDetails
[code]...
how can I create a custom control which is able to generate the named DIV sections "DetailsNameDiv1" and "DetailsNameDiv2" where my custom control can check a condition and make one or the other visible. Also, I need to be able to add controls to these named DIV sections when I host the custom control and the control that I add to the named DIV section needs to let me set values of these controls from the code behind logic of the page (or usercontrol) where the custom control is being hosted (in my example, I am adding TextBox controls that I want to set the Text property from a SQL Data Reader).
I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.
I am building a custom web panel control for specific purpose.I want the control be fixed with specific width and height so that not to be resized in design mode as well as from property window.How can I do this.
View 2 RepliesI want to created a Custom Server Control (Inherited from GridView).
On the page, the GridView is DataBound to a DataSet, so I do not know at design time what columns will be present in my GridView.
Now, what I want to do is, to add a textbox in every Cell for the GridView Header row, and those textboxes will control column filtering.
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.

View 1 Repliescreated 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.
