I'm trying to set the selected value of a ddl during page load ie. before databind.
This causes "selected value does not exist" errors. So I force a databind, and add a new element if it does not exist in the data source.
However it looks like when the databind is performed later in the page lifecycle that my added element(s) are removed/overwritten.
Am I setting the values in the wrong part of the life cycle?
I have a function on page load which will work based on dropdown selected value. and I am using this dropdown in a user control. So getting problem because the dropdown value is not loaded yet before Page Load. How Can I do that using those control still.

I am developing a web site that has holiday prices which are taken from a different database and loaded into two SQL databases.I have two girdviews to display each of the prices data.What my issues is that I need to load an SqlDataSource on database 1,when 'Family' is selected from a dropdown list and run an SqlDataSource on database 2 when 'Themed' is selected and then run both when 'Don't Mind' is selected.
Question basically crams it all in... I'm loading a page with a querystring (ID), and I need to use that ID to set the selected item of a ListView when the page loads. The ID is a DataKey on the ListView. I have no code of value to post--none of my attempts at this work.
View 2 RepliesI'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
View 1 RepliesIn my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}

ajaxToolkit:CascadingDropDowns.
The dropdowns are working perfectly fine with the web service methods. i.e country loading initially and then State as per selected Country and City as per the selected City.
The problem occurs when I try to set selected values in these dropdowns as per the Values previously saved.
The Country loads properly and the selected value is set according.
The State is filled as per the selected country but its selected value is not set.
The City is not loaded at all (as the state doesn't have a selected value)

ddlGameName is the dropdown that the user selects from which calls the postback and then updates another dropdown.
