I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.
But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.
I got one web page which is developed by using Asp.net. and in that page I have got one tab control which developed by using Ajax control toolkit (tab container). In that tab container i have got three tab pannels. In the first tab pannel have got two drop down list boxes and one image control box. wat I was trying to do is that by using calendar extender control in ajax control toolkit i was trying to display a day in the first drop down list box and month and year in second drop down list box. when user click on image control during run time a small calender will pops up and then user will select the propective date according to there choice and when they have finish selecting the date from the calender a day will display on first drop down list box and month and year will display on second drop down list box.
I was keep trying to do that but i was failed. then i took one test box from the toolbox and i was got success in displaying the user selected date in the text box by using ajax calender extender. How to display that date instead of one textbox into two separate drop down list boxes from which a user can select manual date from drop down list as well and from the calendar as well also when the page loads, the two drop down list boxes must show current date ( by default)
I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
I have a RadioButtonList and two cascading dropdown linked to corrspoding dropdown control. Based on radiobutton's selection, the cascading will be prepopulated with some values and one value is selected in both dropdown.
I want to disable the cascading dropdown/dropdown after values are filled and selected on selection of radiobutton selected in RadioButtonList.
I tried to disable it, but in that case dropdown is getting empty.
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement
On my current project I want to deny going back once my customers hit submit button and redirected to the final page. How can I deny from going back to previous page or some mechanism to expire the page if the back button is clicked. I tried this code and it didn't work
I have a Gridview that has a button at the left hand side representing the row number. The Gridview has two textboxes and a dropdown listbox as templates. I would like to enable or disable the textboxes and the dropdown listbox if the row is not selected. I also need to enable or disable the templates depending on what the value is of one of the cells. When the templates are changed, I need to save the changes.
I have been able to get this working in the RowDataBound Sub but not in the RowCommand Sub when the row is selected. provide an example in VB.My current RowDataBoundSub, which does no work is below:
Protected Sub PropGrid_RowCommand(ByVal sender As Object, _ ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles PropGrid.RowCommand[code]....
My current RowDataBound Sub, which is working is below:
Protected Sub PropGrid_RowDataBound(ByVal sender As Object, _ ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles PropGrid.RowDataBound [code]....

I have a main "index" view that has a drop down and a submit button. When a selection is made (CampaignId) and a submit button is pressed a list of items is displayed and filtered based on the selection from the drop down list.
I've added a partial view (on the right rail) of my site that lists a bunch of campaigns. when a link is pressed in that partial view a (CampaignId) is passed to my page and the same thing happends as if you would make a selection from the drop down. The issue is that the dropdown "Campaign Name" should be selected based on the selection from the partial view.
