Change The Default Assignment Of Field In TreeView Control?
Jan 26, 2010
I have this code setup currently:
TreeView tree;
TreeNodeBinding treeNodeBinding = new TreeNodeBinding();
treeNodeBinding.TextField = "Name";
treeNodeBinding.DataMember = "Address";
treeNodeBinding.ValueField = "Zip";
treeNodeBinding.ToolTipField = "FileName1";
tree.DataBindings.Add(treeNodeBinding);
tree.DataSourceID = "Customers";
tree.DataBind();
The datasource (XML) may or may not have an optional attribute called IsPremium. If it exists, then I have to add custom business logic that determines what the treeNodeBinding.ToolTipField is going to be. The custom business logic will generate a string which needs to be set as the value of the ToolTipField.

In my webapp, I have a DropDownList_OnSelectedIndexChanged that assigns values for a number of <asp:textbox'es depending on which entry is selected...
public void ModifyProjectIDBox_SelectedIndexChanged(object sender, EventArgs e)
{
int tempJobID = Get_Selected_Report();
dbCommandString = "SELECT Name, Address, State, Awarded, StartDate, EndDate, HomeLocal FROM dbo.ProjectInfo WHERE ProjID = " + tempJobID;
dbComm.CommandText = dbCommandString;
dbConn.Open();
dbReader = dbComm.ExecuteReader();
dbReader.Read();
ModifyProjectNameBox.Text = dbReader[0].ToString();
ModifyProjectAddrBox.Text = dbReader[1].ToString();
ModifyProjectStateBox.Text = dbReader[2].ToString();
ModifyAwardedBox.Text = dbReader[3].ToString();
ModifyStartDateTextBox.Text = dbReader[4].ToString();

i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message :
Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control
public class CmdTest : CompositeControl
{
public virtual FormView HeaderControlName
{
get
{
object oObject = ViewState["HeaderControlName"];
return (oObject == null) ? null : (FormView)oObject;
}
set
{
ViewState["HeaderControlName"] = value;
}
}
protected override void CreateChildControls(
{
Controls.Clear();
Button xx = new Button();
Controls.Add(xx);
}
}
webpage.aspx (assign FormView1 in design time, it will generate error)
<Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" />
webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works)
<Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" />
Webpage.aspx.cs
protected void BsCmdTest1_Init(object sender, EventArgs e)
{
CmdTest1.HeaderControlName = FormView1;
}

I have got a composite control and i would like to dictate which attribute/property is assigned to the control first from the markup?example in the aspx file:
<MM:MyControl ID="" runat="server" ViewType="normal" BaseType="RealBase"></MM:MyControl>
when the control gets created from the mark-up above, ViewType will be assigned first, Which is what I do not want, I would like RealBase to be assigned first under all circumstances. This control is to be users by other developers so I cannot just switch the order.

Is there a way to add/delete/update the default classes (for instance AspNet-Menu-WithChildren,AspNet-Menu-NonLink ) of the html generated by the asp.net menu or treeview control? I am using CSSAdapters so the menu control renders in a list format instead of table format.

how I can set a default view for a treeview. meaning I have a treeview created and has some data in it. when the page first loads it just shows the treeview. I need to actually display the very first node's data. So i have the treeview, with a parent node and 3 child nodes. I need to dynamically get the the parentnode and then get the first child node and display that data without clicking. I could just hard code the path in, but since this is still in development more nodes will be added and there for the order could change.

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.

I'm using asp.net list control that creates a table with <div> elements that have a picture thumbnail, and when the user clicks on the div and it calls Ajax method and populates a shared dialog with correct information, and then shows it to the user. In order to do this the div needs to know the item id associated with it, so it can do the db lookup.
how do you dynamically store data to a div item in a list view loop.
so something like
<listControl>
<ItemTemplate>
< div>
stuff
thisdiv.data(<% Eval(id) %>); // <-unsure about this part
</div>
</ItemTemplate>
</listControl>

I am in need of validating a TreeView to make sure that users have selected something. What I need is something that mimics a RequiredFieldValidator and stops a page from posting back with any data until something is selected.
I am using C# and ASP.NET 3.5
I have tried this and it did not work for me:
if (TreeView.SelectedNode.Value == null)
{
lblError.Text = "Required";
lblError.ForeColor = Color.Red;
}

I want to make my queries better but have been un-able to find a resource out there which lays out when a query is shipped of to the db.
DBContext db = new DBContext();
Order _order = (from o in db
where o.OrderID == "qwerty-asdf-xcvb"
select o).FirstOrDefault();
String _custName = _order.Customer.Name +" "+_order.Customer.Surname;
Does the assignment of _custName need to make any request to the database?

I am trying to add a bit field with a default value of false to an existing table using VWD 2010 Express. With the allow nulls checkbox turned off and no data in the table, any value I attempt to enter into the default value box (0,(0), ((0)), False) all produce an error when exiting the field. What's the secret?

I have a treeview and I am giving the node style in code behind.
Treeview design is as below:
<asp:TreeView ID="tvIARHierarchies" runat="server" NodeIndent="15" ShowExpandCollapse="true"
ShowLines="True" Width="98%" OnSelectedNodeChanged="tvIARHierarchies_SelectedNodeChanged">
<ParentNodeStyle Font-Bold="False" />
<HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />
<SelectedNodeStyle Font-Bold="true" BackColor="#6f9dd9" ForeColor="White" />
<RootNodeStyle />
<NodeStyle />
<LeafNodeStyle />
</asp:TreeView>
While populating the tree-view I have a requirement to bind the one particular level with a different colour. So, I am binding it as below
foreach (DataRow row in dr.GetChildRows("rsParentChild"))
{
TreeNode cChild;
if (row["NAME"].ToString() != "")
{
if (row["Level"].ToString().Trim() == "4")
{
string strColor = "DarkOrange";
string fname = "<font id=" + row["NAME"].ToString() + " color ='" + strColor + "'>" + row["NAME"].ToString() + "</font>";
cChild = new TreeNode(fname, row["ID"].ToString());
}
}
Now when the tree view loads, the required level 4 nodes are populated in DarkOrange. But, when any node is selected the backcolour changes as #6f9dd9 as per the style specified in the markup. But the fore-colour does not change.

I am new to .NET and MVC, so this is most likely a simple question: How can I have a default value appear for an Html.TextBox or TextArea field, for example if the code is currently - <%=Html.TextBox("ApplyToFax", Model.Competition.ApplyToFax, New With {.class = "regular", .maxlength = "50"})%>. I am looking to have a default fax number appear in the box when the page loads, for example (999) 999-9999.

.NET newbie. I know there has to be a way to do this.I have a details view with it's default mode set to Insert. This is to be used as a form for users to enter records into a database. For two of the fields, I want to pre-populate the field with information. Specifically, I have a vb script with a few functions to query Active Directory to return the user's name based upon their user id. This script works fine.I call the functions for the user name like this:
<InsertItemTemplate>
<asp:TextBox ID="txtUserID" runat="server" Text='<%#CurrentUID() %>'></asp:TextBox>
</InsertItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="txtUserName" runat="server" Text='<%# GetUserName(CurrentUID()) %>'></asp:TextBox>
</InsertItemTemplate>
When the page loads, this populates the text boxes with the user id and the user name.But when the form is submitted, the values in the text boxes are not inserted in to the database.How can I set default values for the fields when the values come from functions?

This may be a simple question but here it goes. I have an insert form that captures the current date of entry. What I would like to do is not cause the user to enter or select the current date but have it display on page load and capture to the field in the table on submit.I am rather new to ASP and am using Visual Web Studio 2008.

My web-based app allows users to override values in certain textboxes. If they don't override the value, the system will display (and use) a default.
I would like to support a scenario where the user has overridden the value, but now wants to revert back to the system default value, but doesn't know what value to enter. I would like to provide an intuitive UI for causing the system to revert the field's value back to its default.
Fields occur both on edit forms (where space is plentiful), as well as on edit grids (where space is scarce).
Requiring the user to clear the field is not an option, as sometimes the user's override is an empty value. Would rather not use a keystroke, like Ctrl-Z or ESC.
Best thing I can think of is the user hovers over the field and a popup displays giving the user the option to use the system default. I could use the same popup to capture/display a comment related to the override.

So question from a Newbie !So I have a web page with a Details View component for Inserting data into a table.One of the fields is a date/time which I want to be now().SO I guess there are 2 ways of doing it - either I populate the date/time field in the form with a variable that represent now() and make it Read Only so the user can't change it or I somehow make a hidden variable (ie not displayed in the form) that writes a date/time of now() into the database whenever an INSERT takes place.What is the best way and how do I do either of them ? How do I make one of the fields in the INSERT form of the Details View a preset variable ?
