Here's the Design View: I'd like to add code in the code behind to perform additional edits. I added the "ErrorMessage" LiteralControl. How do I access it from the code behind or is there a preffered way to display a custom message using the control's functionality?
is it posible to add client side functionality to a custom server control in vb.net?i am looking at msdn library and there is no code for vb :/ http://msdn.microsoft.com/en-us/library/aa719700%28v=VS.71%29.aspxI fount this on MSDN Library Adding Client Capabilities to a Web Server ControlWhat i'm trying to do is to add some client functionality to my control, so that you can get or set some properties/values on client side. From the above link i see that this is doable with Ajax Server Control, but i don't have it, i have Custom Server Control. Can i do this with Custom Server Control and how?

I am using the SQLMembershipProvider for authenicating users for my web site. I would like to change the default message that is displayed when a user signs in but who's account is disabled. By default, it shows:

Is there a way to display a "default" message on a MS Chart Control if there is no data to chart?
I have a chart, with some controls that allow the user to pick various date ranges. If there is no data to be charted in that date range, it currently just displays nothing (or at least it shows the legend, and background, but that's it.)
I want there to be a message saying "no data for this period" or something instead.
Is there any asp.net flash control which will work on client side without installing flash plugin.Actually i was using flashcontrol in my project and thereby displayed swf movie in my project . It was working right on server because flash player and flash plugin were installed on it. But when i tried to access that page on client side it doesnot showany movie or image
I've got a CreateUserWizard control and am performing server-side validation. Is there a way to force the CUW's error message to display from the code-behind? At the moment, if the user enters a duplicate name, the controls DuplicateUserNameErrorMessage property is displayed. However, if the user has turned javascript off, or sends a custom POST header, with invalid characters, I rely on my server-side validation to catch the error. How can I then display the same error message in the control's ErrorMessage label, instead of creating a custom label and faking it?
I have tried in many way but the error message for custom validator is not shown in validation summary but it(ValidationSummary) shows error message for every other type of validator.
The client has requested that the password Text Indicator (displayed to the right of the control) doesn't dissapear when the password control looses focus. I can see his point on this.
here is the problem I have:There are 2 textboxes: uxActiveDate, uxExpireDate. Expiredate has 2 validators attached to it:
In the markup:
[Code]....
In the code behind file: [Code]....
The problem is when expire date is selected before active date, and current date, then both the error messages are displayed. I have to set priority or something so that these 2 messages are not displayed at the same time. Is it doable?
PS: Since if required field validator does not pass, then other validators dont execute, I guess there is a way to set priority so that if one validation is not passed others will not execute. Validation summery is not an option, since it does not show message client side.
I have used standard asp.net roles and membership provider in my asp.net mvc project. The resources like creating an employee and setting its role can only be done by administrator. Now at first delivery of software to client, there will be no user, i want to implement a functionality where if there are no users in the system user can directly create new employee and assign roles without logging in. Once the roles are assigned user will have to log in to access authorized resources. Can i implement custom action filters that will assist me in implementing this functionality? How can i impelment this functionality?
I was wondering if anyone can point me in the right direction? I have a POCO model and I am using Code First CTP. In my application, I set the database to be recreated whenever the model changes.
I would like to write custom functionality to access the model (POCO) metadata same way as EF sees it and use that to generate some source files (using T4). I would like to access the processed model not having to worry about finding properties that hold primary keys or any other conventions (implicit or not). What is the way to go about it?
I am trying to create an ObjectList (on Form1) that will have a "Select" link (command) in the 1st column, the name of the application in the 2nd column, and the 3rd column will be the applicationID that will be hidden. I have tried several times but can't seem to get the display and functionality that I am wanting to work. For the functionality, on a command event I will get the applicationID and redirect the user to the another page passing the applicationID.
I have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.
I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".
I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:
protected override void OnPreRender(EventArgs e) { // Do as usual base.OnPreRender(e); // Adjust each data row foreach (GridViewRow r in Rows) { // Get the appropriate style object for the row TableItemStyle style = GetRowStyleFromState(r.RowState); // Retrieve the reference to the checkbox CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID); // Build the ID of the checkbox in the header string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID); // Add script code to enable selection cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')", SelectedRowStyle.CssClass, style.CssClass, headerCheckBoxID); // Update the style of the checkbox if checked if (cb.Checked) { r.BackColor = SelectedRowStyle.BackColor; r.ForeColor = SelectedRowStyle.ForeColor; r.Font.Bold = SelectedRowStyle.Font.Bold; } else { r.BackColor = style.BackColor; r.ForeColor = style.ForeColor; r.Font.Bold = style.Font.Bold; } } }
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.
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.
