Web Forms :: Setting Default Value Of Dynamic Dropdown?
Jan 10, 2010
I'm binding data to my dropdown as follows:
[Code]....
So my dropdown will be populated with a list of years that could be different depending on the SchoolID passed in. I want my default value to be the max returned in the SELECT query minus 5 (so in other words, the max index minus 5). For example, if my list of years was:
i have a country dropdownlist (asp.net server side control) where in i wish to set United States as first country from list of alphabetical countries in drop down. How should i do that?
Plus on selection of country the respective state gets fired up. So if USA is selected in country by default, the states need to be selected by default (Of USA of course!!!)
I am not trying to achieve anythign fancy but just trying to set default selected value for one of the dropdown that I am using. for that I am doing Items>selected= true for whatever item I want selected when i load the page. In my case, it is a month dropdows and I am selecting date 14 as selected default value out of all 30 values but somehow, out of the blue .NEt decides to show me 29 instead of 14. I am not sure if there is some another setting that is overwritting this value.
I have two login control in the index page of my website,each of two different usertypes. there are two user types brands and creatives.the branded user will log in to brands bin(brandsbin.aspx) the Creative user will sign in to creativebin(creativebin.aspx) i am using forms authentication for signin. so i am confused here to to rediret to default path for each user types. how to set default page for each user types. in the web config file i have added like this
I'm trying to set the default button to my master page for logging in.
Basically I've got a master page, with a LoginView in it, with a Login control in it, With a button in it... When you press "Enter" I want it to use that as the default button.
(structure in sudo-code if it helps)
BODY Form ID=Form1 LoginView ID=MasterLoginView AnonymousTemplate Login ID=MainLogin LayoutTemplate Button ID=LoginButton
I know I've got to use .FindControl("") but as much as I mess with it I can't seem to get it to hook to the button.
I would like to set a default date, not the current date ( say 31/11/2011) for the calender control. What date format should I be using for the datetime variable so the calender control accepts the date. I have tried using the following date format but I keep getting the error: String was not recognized as a valid DateTime.
[Code]....
Or is there another way to set a date for the calender control.
I am trying to find a way of setting a default image(e.g. file path) for the FileUpload control so that a default image can be used if a user did NOT choose to upload an image.
In one of my content page , i have two divs - div1,div2.
On page load , only the div1 will be visible. On clicking a button inside it the div1 is made to invisible and the second div- div2 is made visible.
At the page load , i want to make the button inside the div1 to be the default one. On its click i want to make the button inside the div2 to be the default one .How can i do that?
I've got a user control with a dropdown of states. I have a State property that sets the selected value. When I add this control to a page and set the state property, it doesn't set the selected value. If I add some code in the page load event of the user control it does set the selected value.
i am having a radiobuttonlist in datalist and i am binding values to radiobuttonlist.. when i select particular radiobuttonlist, corresponding image should be displayed..i am having difficulty in setting default selectedindex for the radiobuttonlist

I have a DropDownList that is bound to sql datasource . How can i set its default value to Null and change its value to one of its items programmicaly.
Using Microsoft Visual Web Developer 2010, I have created a SQL database, with the goal being to create a Lead Management system for my company. I have created two columns: 1 is named InitialCall, and the other is named FollowUp. The InitialCall column has a datatype of "datetime", and currently, the default value setting is (getdate()). The FollowUp column is set to varchar(max), because I want to allow a sales rep to add whatever information they want to.
What I would like to do is change the default value setting in InitialCall from (getdate()), so that it will update that field whenever a sales rep upates the FollowUp field. In essence, this would create a time stamp so that I would know the date and time that the sales rep followed up with a particular lead. What would I enter the default value as?
I use a dropdown to select a record and set another dropdown to a preselected value as mentioned in the record. But when I initiate the record reading, it gives me the following error which I can't resolve. dd.. has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
[Code]....
The vb code related to the selection dropdown is: [Code]....
I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.
I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).
I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:
I have a dropdown list that is populated by a dataset (Data being extracted from DB). Based on the selection made by the user I call OnSelectedIndexChanged, and populated the form with the relevent info. The problem I am having is the first item in the list is selected by default, so if the user selects this option OnSelectedIndexChanged does not fire. To work around this I add a default item to the dropdown list after populating it with the dataset as shown here;
jobStandardActList.Items.Insert(0, jobStandardActList.SelectedIndex = 0; jobStandardActList.SelectedValue = "----Select an Item----");"";
This works fine, however if the user selects an item from the list, and then proceeds to selects the default item "----Select Item----" i receive an error. sys.webforms.pagerequestmanagersevererrorexception: an unknown error occured while processing the request on the server. The status code returned from the server was: 500
I want to have a default value/item of "---Select One---" and then list all of the values from the SQL statement. Currently I am having trouble doing this. I tried to add it to the List Item but it doesn't show on the page.
I have a date list in DropDown and there is no blank item in it. Dropdown item seems to be following:
01-02-2010 02-02-2010 03-02-2010 04-02-2010
DropDown is bounded by sqlDataSource.
If 04-02-2010 is the last date for today then I want to display 04-02-2010 by default in the dropdown if the page load.
We are updating data on daily basis. So on next day the date will be 05-02-2010 so when the data updated then 05-02-2010 should be shown iby default in the dropdown.
Is there a way of setting the default unchecked value of a checkbox? Am not using a databound control. This is passing data from a form and would like it to pass false as opposed to null when unchecked.

I am in need of some assistance in regards to how to best set the values of properties for a Web User Control which is being included into a cell of a GridView with dynamically created columns. I have tried a few different approaches, but can't seem to get a satisfactory result. Also, to be completely honest, I am not really sure if I am using best practices for what I am trying to accomplish.
First off a little background:I have a GridView for which we will never know the exact number of columns at run time. The columns are predicated by user selection. I am creating the command text for the DataSet on the fly and then looping through the columns of the resulting DataTable in order to use custom TemplateFields. This works ok for just printing out the row values but not so much for when I need to insert the Web User Control into a cell.The Web User Control is in essence a collection of image links which are used as a "Quick Nav" tool. I need to pass the values of 2 fields from each DataRow to the control via properties (for example, CustID and ProductID). I am using custom TemplateField classes inheriting from ITemplate for displaying my fields and extending the DataBinding event like so: [Code]....
This won't work for my User Control as DataBinding is called after the control is loaded into the page and I need the properties to be set before the Page_Load event of the control is fired.Is there a GridView event I should be looking into instead such as RowCreated or RowDataBound? Or should I modify how I loop through the DataTable by doing rows first, then the resulting columns as I've seen done elsewhere?
