Web Forms :: Unable To Change Textbox Values After Manual Assignment?
Sep 21, 2010
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();
ModifyEndDateTextBox.Text = dbReader[5].ToString();
public void ModifyProjectIDBox_SelectedIndexChanged(object sender, EventArgs e)

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.

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.

I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....

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 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've done a bit of development with C# applications but not much with ASP.Net so if this is a trivial issue. I have a webform that has textboxes for password, phone number and a listbox for a provider. When I load up the webpage, I populate with the textboxes and listbox with selections from my SQL database. This works correctly. Then I allow the user to change data in any of controls. In the event that is triggered by the Save button, the values in the textboxes and listbox are the data values that were populated during the loading of the page, not what the user has typed in.
What am I doing wrong? I've attached my 2 pages of code.
Here is the .aspx

I'm trying to use a javascript Date and Time calendar in my Insert and Edit templates in a Detailsview that is bound to SQL Fields. The reason I am trying the javascript date time selector is that I need to have the date and time, the asp.net one is just the date part.
I tried using it with an asp:textbox on just a plain aspx page and it works like a charm, however when I add it to the detailsview i keep on getting the "Error: Object required" am I missing a step here? That and seeing as I'm using a site master page where exactly do I put the:

I have a shooping cart in version 9.0.1.3
I have several products with two variants for each.
I can add any quanity to the first variant and it is calculated into the cart correctly.
When I try to add a number besides one for the second variant it will only show one of the porduct in the cart.
I can change the quanity when it is in the cart. But I need it to work correctly.

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 a GridView on my page and I have bound a custom DataSource (DataTable populated from an SQL query) within an UpdatePanel. I have set the OnRowUpdating property and create the code behind stuff as well as setting AutoGenerateEditButton to true. The problem I have is that when I click on 'Edit', then change some values then click 'Update', I can only get the old values.
.ASPX
[Code]....
All of the other posts I have read have mentioned the GridView being bound on post back or within a RowDataBound event but I'm pretty sure that I am not doing that.The RowUpdating event does fire but the value of Jockey, for example, is still the original.

I have a page (page1) with 4 controls that serve as the parameters for a report. The submit button does a cross page postback to another page (page2) that contains a ReportViewer control.Unfortunately, I cannot read the values from page1 once I get to page2. Here is the source to page1:
[Code]....
Here is the handling code on page2 (rvProjectStatus being the ReportViewer control):
[Code]....
In other situations I have passed such values in the query string and then assigned them to the parameter collection, no problem.Also, please note, I have tried using the @PreviousPageType directive to get at the types on page1, but have met with no success there either.
