• Henry_Yang Find the ID of the dynamically created controls

  Hi,               This is the requirement. I am trying to create the controls dynamically based on the values in the Database.   I am able to create the controls successfully.   I have a repeater control in the ASPX page.   On the Header Template, Item Template and Footer Template, call a class Template. On Databinding of this Repeater control, calls a method inside the class Template.   This method creates the controls dynamically, & adds them to the place holder.   In creating the dynamic controls, there are dropdown list controls. Based on the value in the Dropdown, I wanted to hide certain controls.   F ...Show All

• Enkht How can I resize controls at run time by mouse?

  I have some controls on my Form such as Treeview and ListView. Now I want to resize them at run time like Outlook Express but I do not know how to do that. Please tell me the way to do that. Thanks in advance! Phuc Pham. Hi, if you are using .Net 2.0 you can use the SplitContainer control, you can then change its Orientation property to either horizontal or vertical to achieve the effect you want. By docking/anchoring the child controls in either panel they will resize and you move the splitter. Mark. Hi, what do you mean exactly by resize, as in some kind of splitter window where you can move the separator bar to show more or less of the tree If so then user the Splitter control. It will allow y ...Show All

• SunilN "PropertyGrid" problem

  Hi there, I've created an expandable "PropertyGrid" control that initially looks like this when fully expanded -Name -Dimensions 10,20 Width 10 Length 20 As soon as I type in something for the "Name" property however and press <Enter>, the grid then looks like this: -Name Whatever +Dimensions 10,20 Width 10 Length 20 Notice the "+" that now appears beside the "Dimensions" property. The grid automatically collapses the "Dimensions" property IOW (why ) but doesn't clear out the "Width" and "Length" beneath it. It appears to be a cosmetic problem only since if I call " ...Show All

• jhapps Control.InvokeOnClick and Validation of a Form

  I have a Form with a WebBrowser control on it.  Since the WebBrowser control seems to muck with certain hotkeys that I want to use on a navigation panel (full of buttons with ALT+<KEY> accelerators), I've overridden the ProcessCmdKey method of the Form and am intercepting such hotkey codes and mapping them via a hashtable to the appropriate button that I need to programmatically click.However using Control.InvokeOnClick seems to directly call the attached click event listeners rather than attempt a mouse_down followed by a mouse_up event which can be cancelled via a Control.Validating event handler's argument being set to "e.Cancel = true;" . So the problem is the Control.InvokeOnClick never causes the Form or any ...Show All

• Ryan S. Grouping radio buttons

  I'm stuck on radio buttons in C# alas. I can group them by putting then in a Group box, that falls into place. But I want to treat them in code as a group too. I want to be able in one line of code to get the button which is selected, not have to scan through them all one by one. Can this be done Is the group of radio buttons itself available as an object that can be queried with regards to the status of the current seelction in that group Unfortunately there's nothing built-in to do what you want. I would suggest that you handle the Click event for the radio buttons. You could wire up the same event handler for all the radio buttons in a group dynamically so you always have the currently check button without having to query them a ...Show All

• Sanjukta ListBoxes transfering from 1 box to another

  Hi! What I'm Trying to do: Basically, I select an item in ListBox1, click a button, and it'll transfer to the 2nd ListBox and remove itself from ListBox1. I've accomplished this, the problem is if I hit the button, without selecting anything in ListBox1, the program will crash.
