Web Forms :: Passing Values From Databound DropDownList To TextBox
Mar 9, 2010
Let's say I have DropDownList ddlRooms bound to the datasource which returns list of available rooms from table tblRooms. On the other hand I have users, and their info is stored in table tblUsers. Using FormView frmUsers can be inserted, edited and updated... frmUsers is be bound to separate datasource. To each user, I would ilke to assign a room, so the value of txtUserRoom will be populated based on the selected value from ddlRooms. How can i pass the selected value of ddlRooms to txtUserRoom while keeping txtUserRoom stil bound to user datasource? Do I need two separate fileds or can i just put value of ddlRooms into datasource user?

I have a problem I have been googling the entire day and still have no soloution. I have a detailsview with 2 dropdownlists. Fisrt one is ddlCaregory. Second is ddlSubCategory. The value is passed from the first ddl to display the SubCategory linked to ddlCategory. Both ddlCategory and ddlSubCategory are Templatefields. This is also in VB.
The Details view has a sqlDataSource (sdsApplicants), ddlCategory has a Datasource (sdsCategory) and ddlSubCategory (sdsSubCategory). ddlCategories lists the data returned from sds Categories and save any changes to sdsApplicants. I can get ddlSubCat to display the correct SubCatagory bases on ddlcategory sesection but as soon as I try bind it to sdsApplicants I get the following error
'ddlSubCategory' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

Code:
SELECT one, two, three, four FROM tblFixedLine_onenet_callLog WHERE (one LIKE '%' + ISNULL(@one,'') + '%') AND (two LIKE '%' + ISNULL(@two, '') + '%') AND (three LIKE '%' + ISNULL(@three, '') + '%') AND (four LIKE '%' + ISNULL(@four, '') + '%') ORDER BY one, two, three, four
@one, @two, @three and @four are textboxes on my ASP.NET page all of which by default have no value(therefore i assumed NULL).If i test the SQL in the VS2005 SQL Configuration (and put the values in manually) it works but the ASP page returns no results... i assume therefore the Textbox value is "" not Null.

I have a form with a combination of dropdownlists and textboxes that I want to be able to show a user as a summary in another page before submitting to a sql server. Page 1 will have a verify button which will then pass the dropdown and text box info to page 2 where end users will be able to either submit the page or cancel the action. What's the best way to pass the values from page 1 to page 2?

I have a page, which contains 2 textboxes. When i click on the first textbox, i have to open a child window (tool), that contains a gridview control with 2 columns (corresponding to the 2 textboxes). When the user clicks on any row in the gridview, it should send back the 2 column values back to the parent window to the corresponding 2 textboxes. how do i achieve this?

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.

i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.

I've got my Drop down list databound to an sql data source, now I need to change the data in a few of the fields before it gets displayed. I've been messing with this all morning and I can't find anything useful, this is what I've got so far and it's clearly not working.
Protected Sub ddlBookType_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlBookType.DataBound
'ddlBookType.Items.Insert(0, "Any")
Dim i As Integer
For i = 0 To ddlBookType.Items.Count - 1
If ddlBookType.Items(i).Attributes.Equals("mod_cook") Then
ddlBookType.Items(i).Text.Replace("mod_cook", "Modern Cooking")
End If
Next

I'm working in a web application and my page is using a databound formview control. When i first enter the page via my code, I am unable to retreive a value from any of my controls -e.g. when i debug, i see that tbDate.text has no value (see code below). How can I retreive the values from the controls on my page e.g text boxes?
Code:
if (!this.IsPostBack)
{
TextBox tbDate = (TextBox)FormView1.Row.Cells[0].FindControl("txtDate");
}

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.

I've build a Modal Popup extender with a DataBound DropDownList. The only problem I've got is that the DropDownList is being filled in the Page_Load. Even when I put the binding in the Load of the Modal PopUp extender there is no data inside my Dropdownlist.What am I doing wrong here? Because everything should work when I hit the TargetControlID.
