I have a gridview control that has a different background color for alternating rows (done using cssclasses). In the RowDataBound event code, I want to change the background color of a ListBox control in one of the cells to match the row color. I have tried the following (in blue), but it does not seem to work. The listbox control still remains with white background. How may I determine the background color of the row so that I may set the ListBox background to match?

A corollary question is, "How may I programmatically reference an item within a CssClass?" For instance the CssClass is named "datagrid." How do I programatically retrieve the value of "background-color" that is defined in this CssClass?
i have a grid view and i use TemplateField.
when i am in ItemTemplate all the column (7 column) are label so it fit to the current screen
by when i use EditItemTemplate or InsertItemTemplate the coulmn don't fit the the current screen and

but when i drag the ruler to the right size to see more information only the cells are moved but the header coulmn stay so i see the current coulmn with worng header coulmn
i've created a webform with one gridview having connected with the database using datasource. i.e password database with three colomn .
now want to insert the custom dropdown button using server control for each column.
when i select the dropdown list the list should display the value as required.
e.g if i click the uname dropdownlist then it should show the list of names.
if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.
can i get code on this type of question...?
I have three dropdowns for selecting a year inside a user control. On load I specify the selected value for one drop down. The other two drop downs are automatically getting assigned the same selected value. No matter which dropdown I assign a selected value to, they all three get the same selected value. I've tried recreating a new user control for the dropdowns but the same thing happens.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DropDownTest.ascx.cs" Inherits="WymanOrgManagement.DropDownTest" %>

<asp:DropDownList ID="ddlStartDateYear" runat="server"> [code]....
why the three dropdowns seem to be in sync?
I need the yoy var %, bm % yoy bps, and opps generated to have a backcolor of gold. before it was a itemtemplate it was easy to change it in the codebehind but now that it is a itemtemplate it wont change anymore.
View 6 RepliesI have a FormView with the following ItemTemplate. What do I have to do to make the Textbox reflect the correct TypeName for the selected campaign?
<asp:Label ID="campaignNameLabel" runat="server" AssociatedControlID="campaignList">Campaign Name: </asp:Label>
<asp:DropDownList ID="campaignList" runat="server" Width="200px" AutoPostBack="True" DataSourceID="campaignsSqlDataSource" DataValueField="CampaignID" DataTextField="Name" SelectedValue='<%# Bind("CampaignID") %>'>
</asp:DropDownList>
<asp:Label ID="campaignTypeLabel" runat="server">Campaign Type: </asp:Label>
<asp:TextBox ID="campaignTypeText" runat="server" Width="150px" Text='<%# Eval("TypeName") %>'></asp:TextBox>
ADDENDUM: I'm trying to do this with zero code. I can make it work if I use a separate data source for the drop-down and the detail fields in the ItemTemplate (i.e. the FormView's main data source), but I can't sync the FormView's data source with the drop-down's selection, because a ControlParameter on the FormView data source can't see control values in the ItemTemplate.
How do I change the BackColor of the textbox area in an asp.net DropDownList from white to another color? The Backcolor property changes only the drop down section.
View 2 RepliesThe Patient Scheduling system I have built extracts current inpatient data from an enterprise health system and merges it with data from a seperate database, based on a common key. This is then displayed in a gridview control for browse/update.
At any one point in time, the client list in my system should reflect the current inpatients in the enterprise system.
The problem is that if the user has not refreshed the client list in some time, there may have been a discharge in the enterprise system and the two get out of synch. When the user selects a client from the list to update, the details of an entirely different client (usually the one below), is presented in edit mode. e.g. if the user selects the 4th client in the list, the details for the 5th client are made available for update.
What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.

My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.
Is it possible to loop through a gridview and based on if a checkbox is checked, then change the backcolor to that current row? I have gave a few attempts, but luck.

I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
The "making the GridView row display it" part is the one that's giving me a hard time.
What's the best way to do this?

I seriously want to learn how to create a custom server control, for that I made a requirement for myself, but lost on how to accomplish it.
Requirement -I want to create a cascading dropdownlist control - which should have following properties -1) ConnectionString - used to get data for the 1st dropdown from database, and also it is used by 2nd DropDown to get data.2) 1stSelectCommand - Used by the 1st DropDown to get data from the database.3) 2ndWhereCommand - used by the 2nd DropDown - uses the selected value from the 1st DropDown in the where clause to get data.
Methods - 1) DropDown1_SelectedIndexChanged()2) DropDown2_SelectedIndexChanged(3) CustomCascading_Changed() - this happens when any of the DropDowns index changed.
PS - This is a random requirement, of course it got nothing to do with any project or real time.I want to learn, so i incorporated basic concepts like Data Access, Custom Methods, Properties etc.PPS - I know how to create basic custom server control, so plz dont forward me links to how to create basic custom server controls. But in case with extrordinary links.
