Web Forms :: Manual Entry In Dropdownlist On Selecting Particular List Item?

Jan 2, 2011

In my project requirement user wants to enter a manual entry if they can not find an item in the drop down list.

Right now what I am doing is:

I set the dropdown list autopost back true and on selectedchanged event I am hiding the drop down list and showing a text box to enter a manual entry...

This is working perfect and no problems..

but the drop down list needs to change to a text box on only selecting a "unknown" option in the list...all other list items are doing unnecessary post back to the server with no use...

Web Forms :: Redirecting A User Selected Item In A Drop Down List To Another Item?

Feb 10, 2010

I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?

If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.

Forms Data Controls :: How To Refresh The Dropdown List In The Details View After The Gridview Item Has Been Deleted

Nov 16, 2010

I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.

all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.

My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....

how to refresh the dropdown list in the details view after the gridview item has been deleted?

C# - Selecting An Item In A GridView And Adding To The List?

Dec 2, 2010

I have written the piece of code below to get a productID from a gridView when the user clicks on the select link.

Convert.ToInt32(GridView1.SelectedDataKey.Values["productID"])))

However, if a user clicks on this more than one click the newer value replaces the previous. Is there a way to keep adding to the cart list when the user clicks on a new item?

Edit:

Here's my code for the Shopping Page:

Web Forms :: Clicking The Label Of A Dropdown List - Resets The Selected Value To The First Item In The List?

Feb 17, 2010

Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.

In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.

How to prevent this one. It should be on PRIMARY Only.

<p>
<tr> <td ><asp:Label ID="lblContactType" Font-Bold="true" Text="Contract Type: *" ForeColor= "red" runat="server" AssociatedControlID="ddlContactType"></asp:Label> </td> <td > <asp:DropDownList runat="server" ID="ddlContactType" DataSourceID="SqlDataSource2" AppendDataBoundItems="true"
DataTextField="TYPE" DataValueField="ID" SelectedValue='<%# Bind("CONTACT_TYPE_ID") %>'>
<asp:ListItem Text="Select One" Value="0" Selected="True"></asp:ListItem>.......

Web Forms :: How To Highlight The Current List Item In The Unordered List

Mar 25, 2010

I have a master page which has an unordered list in this way:

[code]....

These links are directed to my content pages. I am able to highligt the selected list item on hover and on active.

But I do not understand how I can highlight the selected list item as long as the user is on that specific page/link (current list item). I know that we can specify a seperate body tag and id for each of the content pages and then use CSS to highlight the current list item, but all this code rests already inside a body tag in the master page.

MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

Database Table: This data has been imported using Link to SQL
