Forms Data Controls :: Unbound Gridview Row Modify In Rowdatabound Don't Edit?

AJAX :: ComboBox Input / When leave The Combobox It Adds To The Combox List?
Dec 3, 2010I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
VS 2010 - When Selecting Default Option For Combobox 1 / Second Combobox Is Disabled
Jun 13, 2012I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

Gridview Binding With Combobox's In Header?
Jul 27, 2010 how one might go about binding to a gridview in ASP.Net 4 in a scenario where the first row of my gridview should be the headers, the second should be a combobox for each column and the third is the beginning of my actual datasource.
If you can imagine what I am trying to achieve is an ability to create a binding between each column in the datagrid and another datasource. This binding is created by the user selecting a value in the comboboxes. However no matter what I try I cant seem to achieve this.
HeaderText1 | HeaderText2 | HeaderText3
ComboBox1 | ComboBox2 | ComboBox3
DataRow1 | DataRow1 | DataRow1
DataRow2 | DataRow2 | DataRow2
DataRow3 | DataRow3 | DataRow3

Sort An Unbound Datatable?
Jul 2, 2010Is it possible that once I have created a datatable programatically, I can then sort that datatable before binding it to a asp:repeater? I have a number of records that I have to get from a com object that has not been eliminated. The com object populates an array, then I loop through the array to pull data from my datatbase, adding the db data to the datatable. Then I bind the datatable to a repeater.
1) the array is multidimensional
2) The COM object doesn't sort the data by company ID (which is what I need to do)
Ajax Control Toolkit Combobox In Editable Gridview Selected Value?
Jul 16, 2010I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works
fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....
Combobox markup below
<asp:ComboBox
ID="ProductDescription"
runat="server"
[code]...Answer in vb preferably.
Web Forms :: Retrieving Selected Value From Unbound Dropdownlist?

AJAX :: Unbound Reorder List To Not Postback
Jul 13, 2010Reorder list control cannot be set to not postback? My hope for this control was that I could tie it to a list of data (either a datasource or even a manually created list) and then allow the user to move the items in the list up and down until they liked the new order of all of the elements. They then would click a button to save the updates to the database. Is this possible? It seems that after every reorder there is a postback requried to the datasource to perform an UPDATE, even if the PostBackOnReorder
="false"
value is set.
So if my list is
1 Atlanta
2 Boston
3 Chicago
4 Denver
5 Edmonton
and they want to switch Denver with Boston and then hit the Update List button I could cycle through the list an only update two entries rather than all 5 entries twice (for each Postabk on reorder)

View 3 RepliesForms Data Controls :: Sort An Unbound DataGridView By Numeric Or Date Value?
Aug 16, 2010I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56
13.35
1442.22
...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?
