need to get selected value from dropdownlist,textbox and bind in grid
View 1 RepliesI like to add textbox dynamically based on the user selection in drop down box.
View 1 RepliesI have Gridview and Button Control on Form.i want to Add Dynamically TextBox And DropDownList In Gridview on Button Click Wich is placed outside of Gridview.
When i click on Button -> One TextBox and One Dropdownlist which contains values bydefault 1,2,3 should bind to gridview. Button is placed outside Gridview.
I have a dropdownlist that controls what the users see in the gridview. I want to be able to have the users select "All" as an option. For example the drop down would for years would show: All, 2010, 2009, 2008. How do I code for the user selecting "All"? I am using ASP.NET 3.5 and C#
View 7 RepliesThe intension is to get the all text file names in the drop down present in a particular location. When a user selects any filename from the drop down, it will show the data which is in that particular text file in a GridView.
I've done both the steps and it's almost complete but i stuck on a small issue. Probably because of non-usage of ASP.NET for a long period of time. The problem is, the drop down only selects the default value not other values.Here's my code for DropDown Selected Index Change
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DirectoryInfo di = new DirectoryInfo(@"C:myLogs");

I have 2 Dropdown(say "DD1", "DD2") and 1 Listbox(say "LB") in my web form,value of the 3 controls depend on each other.
"LB1" is dependent on "DD2" value, "DD2" is dependent on "DD1" value.
I want that if user selects "LB1" without selecting "DD2", it should give a message that "please select DD2 first"similarly if user Selects "DD2" without selecting "DD1", it should give a msg that "Please select DD1 first" ,using ASP.NET C.
In my project requirement user wants to enter a manual entry if they can not find an item in the drop down list.
Right now what I am doing is:
I set the dropdown list autopost back true and on selectedchanged event I am hiding the drop down list and showing a text box to enter a manual entry...
This is working perfect and no problems..
but the drop down list needs to change to a text box on only selecting a "unknown" option in the list...all other list items are doing unnecessary post back to the server with no use...
Let me start by saying that I inherited this application and have always struggled make changes to it.I am trying to add a checkbox to a form that when selected would activate a textbox and write the value to .ini file. Here is my code and any help would be greatly appreciated.

i'm using a strongly typed view with a custom viewmodel. this viewmodel contains a collection of books.
public IList<Books> Books { get; private set; }
i'm also passing a select-list to the view. however the DropDownListFor helper class doesn't automatically preselect the default value of the book.
@Html.DropDownListFor(m => Model.Books[i].AuthorID, Model.Author as SelectList)
everything else works, e.g. it does pass the selected value back to the controller.
i figured out a workaround by creating the select list in the viewmodel:
@Html.DropDownListFor(m => Model.Books[i].AuthorID, new SelectList(Model.AuthorList, "Value", "Text", @Model.Books[i].AuthorID.ToString()))
however i don't want to implement this workaround if there is a simpler solution. is there a way that the view can handle values from a collection?
when i click on the checkbox in the gridview column1 the textbox column4 should be enabled author wise textbox should be disabled...........
View 1 RepliesI have a drop-down list that is dynamically filled with a set of values. By viewing the source code in the browser I can tell that this list is correctly filled with the "value" and "text" parameters.
But if I try to retrieve the value using ddl.SelectedItem.Value I get the error "Object reference not set to an instance of an object" which means that there is no parameter in "value" to retrieve ...
Page_Load() contains an "If Not IsPagePostback" in which the list is filled. I don't want to use AutoPostback = True since I want to retrieve the value-parameter when I click a "save" button. I must have missed something fundamental here that I do not grasp ...
The code to fill the list looks like this:
Code:
Dim ds as Dataset ()
ds.ReadXml(the path to an xml file)
ddl.Items.Add(New ListItem("destination", "destination"))
ddl.DataSource = ds.Tables(0).DefaultView
ddl.DataBind()
This snippet does not generate any errors: Everything is printed as it should!
But inside my Submit function I cannot be retrieve the parameter:
Code:
objcmd.parameter.add("?destination ", OdbcType.VarChar).Value = ddl.SelectedItem.Value
I want to select a particular item in a dropdownlist by value, in asp.net using IronPython.
I found I can do it like this
listItem = ddl.Items.FindByValue(x)
if listItem != None: listItem.Selected = True
But I want to do it in one line
I have a table MemberProfile with columns FirstName, LastName, Gender and ComplexionCode.here iam displaying complexioncode as a dropdownlist with values fair, very fair, brown and when user selects a value I want to insert that in to table
I have creted a class( LookUpCodes) and written following code
public static IEnumerable<ComplexionCode> ComplexionCodes
{
get
[code]...
now when I click the button FirstName, LastName Gender are inserting in to the table. only Dropdownlist( ComplexionCode ) value is not inserting.
I have a grid and dropdownlist.I want to filter values in a grid by the selection of dropdownlist.How Can i do this? My code is like this
<asp:DropDownList ID="DDLVisitedVol" runat="server" AutoPostBack="true" DataSourceID="DsVisitedVol"
DataTextField="VisitedVol" DataValueField="VisitedVol"
Width="244px">
</asp:DropDownList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString=""
ProviderName=""
SelectCommand="SELECT [ID],[UserName], [Email], [visitedVol] FROM [HitTracker] where visitedVol=@VisitedVol ">
<SelectParameters>
<asp:Parameter Name="VisitedVol" Type="String"/>
</SelectParameters>
How can i pass the selected value of dropdown list to @VisitedVol.
I am having trouble with DropDownList (and/or DropDownListFor) when using TemplateInfo's HtmlFieldPrefix in a strongly-typed view. DropDownList properly selects the value from the model when the prefix hos not been site. Once I set the value of HtmlFieldPrefix, the value from the model is not selected in the drop-down list.
I am using .NET 3.5SP1 and ASP.NET MVC 2 RC2.
Model:
public class TestModel
{
public string Text { get; set; }
public string Option { get; set; }
[Code]....
Is there something I should be doing differently to have the proper value selected in the drop-down list?
Im working on an ASP.Net web forms application, where I have a form and the Index is working correctly, until I select a value from one specific control, a dropdownlist. After that no matter what control I am on if I press TAB it will go to the URL/Address Bar, from there to the search bar and then again to the URL bar...
View 1 RepliesI have several asp dropdownlists that are populated from a database. I would like it so that when an item is selected it opens a seperate page depending on the selection.
View 5 RepliesI 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 inherited a site which I am in the middle of updating which has a DropDownList and a RangeValidator assigned to it. The data is bound to the dropdown on Page_Load. The values are retrieved from the database so the value property of each item is set to the unique ID of the item in the DB.
The RangeValidator looks something like:
<asp:rangevalidator id="ddRangeValidator" runat="server" ControlToValidate="ddMenu" ErrorMessage="Please select value in range" MinimumValue="1" MaximumValue="100000" Type="Integer">*</asp:rangevalidator>
I have a method which automatically populates this value in jQuery e.g.
$("#ddMenu").val("An Option");
This works, however, when I try to post the page the range validation fails. Then even if I manually select that value, or select another valid value it still won't validate. The only way to make it validate is to select non-valid value and then re-selecting a valid one.
Here is the data binding code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load, Me.Load
If Not Page.IsPostBack Then
Dim ds As New DataSet()
Dim myDbObject As New myDbObject()
ds = myDbObject.ToDataSet() // retrieves all objects from the database

I'm building an application that will be used by a number of different schools who want completely separate databases so I've decided to have multiple connection strings and membership/role providers in my web.config file. In my code, I'm trying to set which connection string and provider to use at runtime for the correct database according to the logged in user.
I'm coming into a lot of bits in my code that previously worked fine, that now don't. For example, I used to use:
[Code]....
But now that I've changed it to this, it doesn't work anymore:
[Code]....
The compiler tells me that AddUserToRole is not a member of 'r'. I've had similar problems not just with Roles but Membership too, like with calling CreateUser.
I'd still like to be able to use all these methods that I was using before which are extremely handy. I just want to be able to set the membership/role provider at runtime rather than use the default one. Am I doing something wrong? Is there a simpler way to go about this?
i've created my own custom model binder to handle a Section DropDownList defined in my view as:
Html.DropDownListFor(m => m.Category.Section, new SelectList(Model.Sections, "SectionID", "SectionName"), "-- Please Select --")
And here is my model binder:
public class SectionModelBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (bindingContext.ModelType.IsAssignableFrom(typeof(Section)) && value != null)
{
if (Utilities.IsInteger(value.AttemptedValue))
return Section.GetById(Convert.ToInt32(value.AttemptedValue));
else if (value.AttemptedValue == "")
return null;
}
return base.BindModel(controllerContext, bindingContext);
}
}
Now within my controller i can say:
[HttpPost]
public ActionResult Create(FormCollection collection)
{
var category = new Category();
if (!TryUpdateModel(category, "Category")
return View(new CategoryForm(category, _sectionRepository().GetAll()));
}
This validates nicely and the correct value for the section is assigned when the model is updated, however it does not select the correct value if another property doesn't validate.
i am creating check box's dynamically and assigning them names like "chk_1" and "chk_2".now if later in my code i want to check if they have been checked how can i do that.if i do something like if chk_1.checked is True then i am getting error that chk_1 is not declared.
i am using VB.net 2.0 i can post my code if needed.
