I would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
View 6 RepliesHow would I setup a dropdownlist to check the dates in the database and populate it based on the years of the dates currently in the database? So if some dates were from 2010 and some where from 2011, it would display a dropdownlist with two options in it...2010, 2011.
I have dates listed in my database for a schedule system and would like to add a dropdownlist so I can only list the dates for the current year by default, then a user has to select a date from the dropdownlist to see any dates from a different year. Otherwise, it just shows all dates, regardless of year...

how to select items in dropdownlist if i bind it from database.
Once i select some items and save in database , after that i want items selected when page reloads that items bind in dropdown.
This is my setup: I've got a dropdownlist of people and a linkbutton next to it to add a person. the linkbutton makes an update panel appear. When clicking save, I want the data to be saved and the new person be selected in the dropdown. As far as I can tell, I have done this properly. After I save the data I refresh the dropdownlist and take the new person's value and set it as the selected value. When stepping through, it shows the ddl with the new person and the new person selected! BUT, when the page comes back, the ddl is unchanged, ie NOT refreshed. I thought it might be something with the Update Panel but I got a similar setup to work on another page! It also works on a nested Update Panel (not shown in the following code). Can you think of why this "deception" is happening?
Here is some of my code.

i have 3 drop down list in my page

DDLstore1.Items.Add(new ListItem("select center", ""));
DDLstore1.AppendDataBoundItems = true;

I would rather not magic string my DataTextField/Values on the dropdownlist after setting up the source as a List collection of objects.
I was thinking I could use the DataSource properties but it doesn't seem to like the couple of ways I tried.
WORKS BUT NOT IDEAL
//set the datasource to the returned List<Cart>
this.cartDdl.DataSource = CartManager.Load(WebProfile.Current.UserName);
//set the DataValueField to the Cart.ID property
this.cartDdl.DataValueField = "ID";//would rather use the obj property Cart.ID
//set the DataTextField to the Cart.Description property
this.cartDdl.DataTextField = "Description";//would rather use the obj property Cart.Description
//Bind the ddl to the datasource
this.cartDdl.DataBind();
HOW I WOULD THINK IT COULD WORK this.cartDdl.DataValueField = ((Cart)this.cartDdl.DataSourceObject).ID; this.cartDdl.DataTextField = ((Cart)this.cartDdl.DataSourceObject).Description;

View 9 RepliesI created this generic method to Bind Controls on my ascx:
[Code]....
I cannot use a for cycle, it must be generic to load several DropDownList or CheckBoxLists on my web user control.
environment: VS2008 When running below code the DDLKlient.DataBind() appends the whole set of names to the already existing list. I.e. I have 2 sets of names in the DropDownList!Question:? what can I do to prevent appending and just get 1 (one) set of names?? is there any refresh option?

Assuming i have two dropdownlists namely: dropdownlistA and dropdownlistB. at page load, i bind values to dropdownlistA. however, depending on the value selected or displayed in dropdownlistA, i want to bind data to dropdownlistB.
Currently, i can bind data to dropdownlistA alright and i already have the required dataset and datatable bind data to dropdownlist. However, dropdownlistB does not bind at page load since the criteria for filling the dataset to bind dropdownlistB (which is the value of dropdownlistA) is not selected. how can i make this wwork.
I am currently considered if this might work. If i were to call the databind for dropdownlistA in a different declared method besides its binding in page load, and select the value from bind in the declared method, would any value be selected?
For example:
In during page load, i call the a method that returns dataset values which i bind to dropdownlistA(caseIDDropDownList). then i call another method (CreateexhibitDataSet()) which contains the dataset values for binding dropdownlistB(exhibitDropDownList). however, i need to define a criteria in the CreateExhibitDataset() method which i will use to generate the dataset values to bind dropdownlistB. if i were to call for the data bind of dropdownlistA(caseIDDropdownList) again in the CreateExhibitDataset() method and pick the value in the dropdown list, would i get any values?
How can i work around this to bind both dropdownlists on page load?

I'm working on web pages that have an ASP DropDownList defined, and on page load the data source is bound to it through DataSource.DataBind(). When I step through the code, the drop down list does not show anything in it, but when the page actually displays, it does have items in the list. When exactly does DataBind() get applied to the control?
The problem is that some of the values returned by the SQL back end have a null Text, so nothing is displayed in the drop down list for that row. I want to just use the Value as the Text, but only if the Text is null. And when I put the code to loop through and do that right after the DataBind(), there is nothing in the drop down list at that point in the code.
I have a complex UserControl with the main purpose to encapsulate DropDownList with a number of properties for advanced manipulation.
List is being populated on PreRender event depending on properties previously were set:
protected void Page_PreRender(object sender, EventArgs e)
{
sourceClient.SelectCommand = this.Property1 ? "exec a" : "exec b";
}
The most used property is ClientID:
[Category("Settings")]
public int ClientID
{
get
{
return Int32.Parse(DropDownList1.SelectedItem.Value);
}
set
{
DropDownList1.Items.FindByValue(value).Selected = true;
}
}
Getter commonly is being called by ControlPameters in SqlDataSources on pages with this control.
Setter - from markup: <uc:UserControl1 runat="server" ClientID='<%# Bind("ID") %>' />.
Why does setter from Bind is called earlier then PreRender? And DropDownList is empty and item selecting doesn't work! How to workaround this behavior?
I use these code in my page_load event
while (_dr.Read())
{
txtarticle.Text = _dr["Name"].ToString();
CKEditorControl1.Text = _dr["Description"].ToString();
And this is my table in database

We are building an ASP.NET application with C#.net language and Oracle 9i database. Here we installed Oracle 9i client software on our PCs.We never worked on Oracle 9i database. It's the first time.We are planning to build stored procedures in Oracle database and call them from our ASP.NET application. Does working with Oracle stored procedures and ASP.NET is similar to that of working with MS SQL Server stored procedures and ASP.NET?
