how to make a item the default from a dropdownlist, I want to make the value GBP as the option selected when the page loads, i've spent all day trying to get ddlist to work and now i'm stuck on this.
this
.ViewData["ddlCurrency"]
= new
SelectList(ws.ToList(),
"dboCurrencyID",
"dboCountry",
new
SelectListItem
{ Selected = true,
Text = "United
Kingdom (GBP)", Value =
"GBP"
});
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 bind dropdownlist in my page
protected void Page_Load(object sender, EventArgs e) {
BindDropDownList(DDL1, "city1", "name", "ID");
DDL1.Items.Insert(0, new ListItem("select city", "0"));
}
And SP
LTER procedure [dbo].[city1]
as
begin
select id,Name
from city
end
And design code
 <asp:DropDownList ID="DDL2" runat="server" CssClass="daddsd">
</asp:DropDownList>
And here is imagebutton code that when click on it update data into table
protected void ImageButton_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode2"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
[Code] ....
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
 DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
I am producing a List(Of SelectListItem) from my database and passing this to a DropDownList Html Helper method on my View via the controller.This works ok but I seem to have found a bug or issue where the DropDownList ignores the Selected property of the SelectListItem objects in the list.I have a provider class in my model which will read the database, create the List(Of SelectListItem) and then depending on whether or not the user is associated with one of the options, I will set the Selected property to True for that item.

I wish to pass values of the selected items into a database and however noticed that the selected item is not what is sent into the database you can see in the snap shot below. during run time the following value is recorded. Where did it all go wrong with the dropdown lists selected item? Counting on your intelligence.
View 3 RepliesI used below code to set default value for DDL
state.Items[1].Selected = true;
now I use cascading for DDL how I can same thing for cascading?
<cc1:CascadingDropDown ID="CDLdistrict" TargetControlID="DDLDO" PromptText="All"
PromptValue="" ServicePath="../ServiceCS.asmx" ServiceMethod="GetDistrict" runat="server"
Category="District" ParentControlID="DDLzoneO" />
I tried using the the New ASP.NET Default Web Template in Visual Studio 2010 but one issue I'm encountering is with the CSS selected menu item and read apost which stated that...
"This screenshot demonstrates some of the styling options provided by the CSS, including the style for the selected About menu item"...In the screenshot the "About Us" menu item is highlighted but the page's content is the "Home" page content, not "About Us" page. My problem is...I can't get the selected item to be highlighted as in the screenshot even with fresh site using the built in template.
I have this code:
<asp:RadioButtonList ID="rblExpDate" runat="server" >
<asp:ListItem Selected="True" Text="No expiration date"></asp:ListItem>
<asp:ListItem Text="Expires on:"></asp:ListItem>
</asp:RadioButtonList>
that I would like to be always, on page load, to mark the first option ("no expiration date"). However, if the user marks the second option and reloads, the second option is selected, even though I do this on page load:
rblExpDate.Items[0].Selected = true;
rblExpDate.SelectedIndex = 0;
I am using aspnet menu control and i want to hide the item initially on page load and show the item after an event is trigger say button lick event Can any one give me an example?
View 6 RepliesHere is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx
I'm creating user controls that i will put into an update panel and make them visible only when required using triggers. Once visible it will float in a dialog box so it has a close button which will just hide the control on client side.
The controls have multiple post back states, like a wizard, i'm using a multi view control to accomplish that. My problem is that once the user is at step number two in the control, if the user closes the dialog, than opens the dialog again, (note that the control is made visible on the server and reloaded by updating the updatepanel) the second step will still be displayed. The reason is . because whenever there is a postback the control will load its state using the viewstate, even if EnableViewState is false it will still load it using the LoadControlState method. so my quesion is how can i force a user control to load fresh with its default values without any postback data.
I have the following placeholder in my main master page. I would like to not have to duplicate my news content in several content pages, so I choose to simply not provide this content in them, and the master page should provide its default.
<asp:ContentPlaceHolder ID="SideBarContent" runat="server">
<asp:GridView ID="newsGrid" runat="server" AutoGenerateColumns="false" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</asp:ContentPlaceHolder>
When I try the following code, I get an error because newsGrid is null. I assume I'm doing this at the wrong place in the page lifecycle, but I don't know where the right place is.
protected void Page_Load(object sender, EventArgs e)
{
Page.Header.DataBind();
if (!IsPostBack)
{
newsGrid.DataSource = _newsService.ListActive();
newsGrid.DataBind();
}
}
I create a website with enable default content page. the default content is login page index.aspx. During testing, I found one interesting issue. If I type the URL in browser without specify the page, the site is working fine.
[URL]
If I change the url with specify the default entry page, index.aspx, the login page is working correctly. The problem is, in navigate to another page, I can see one Get index.aspx request send back to server. I don't see this 200 request in the previous test. Why? is that anything wrong?

In 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();
}
}

Based on my dataset row value , my drop drown will focus the particular list item in page load event.
ddparty.SelectedIndex = ddparty.Items.IndexOf(ddparty.Items.FindByValue(ds.Tables[2].Rows[0][1].ToString()));

I am building master page in the wwwroot directory and also i have AboutUs folder in wwwroot directory.
I have default.aspx file in AboutUs folder, and it is using master page , but when i run default.aspx file then it does not load header image, which is part of master page.
can someone tell me why header image does not get load? and everything else from master pages gets load?
I am sure this is something to do with file path?
i'm doing a website project for my studies .
and i'm going to work with frames instead MasterPage.
now, how do i load a page in the frame from clicking on item in the menu.
I have a GridView that I would like to load at a specific page that has an item with same ID as the QueryString parameter in the URL.
View 5 RepliesI am using frames in my webpage.in one of the frames i have a menu control whose items are database driven.when click on the menu item, i want another page to be displayed in other frame. now i want to pass the the selected menu item text to the other page using session variable which is in the menu item click event method.but the thing is when i click on the menu item, the click event is not firing. is there any better way to pass the selected menu item text to the other page?
View 1 RepliesI need a way to change the ActiveViewIndex of a multiview control based on some query results. Right now I test to see if I have rows returned from my linq query. If so, set a certain view active. If no rows are returned, I would like to set a different view active. I would like to do this on Page_Load if possible.
Right now I get the fatal "Object reference not set to an instance of an object" error on page load with it bombing at line 12. My count is given a value at runtime so that is not the issue. Can anybody tell me why this is and how to get around it. Code is attached.
I also tried this both the pre render and Page_Init event but both yielded the same behavior with the Object reference not set to an instance of an object error. I can do this just fine in an onclick event for a button, but now I need a way to run a test and set the default view when the page loads. Seecode below
protected
void Page_Load(object sender,
EventArgs e)
{
eCrystalPSGDBDataContext psgDB =
new
eCrystalPSGDBDataContext();
int count = (from st
in psgDB.studyTbls
where st.patientid_i ==
Convert.ToInt32(Request.QueryString["PatientId"]) && st.studystatusid_i
== 1 select st).Count();if (count == 0)else
if (count == 0)
{
StudyInfoMultiView.ActiveViewIndex = 1;
}
else
{
StudyInfoMultiView.ActiveViewIndex = 2;
}
}
I am using the code provided on the web portal for nested gridview and its working fine too.
But I want to make the child row expanded on the first page load how to do that..
