Web Forms :: Retrieving A Property / Variable From A Webpart Usercontrol?
Jan 19, 2010
I need to read a Property/variable from outside the webpart usercontrol to determine a course of action. This is not the same as using the Property Editor.
I have numerous usercontrol webparts all accessing the database.
When minimised, I don't want the webpart to hit the database.
So, I need to either : detect within the usercontrol webpart itself that its chromstate is minimised and therefore not access the database (and)or from the Webpartmanager loop through webparts, determine those that are minimised and set a variable / property within the webpart to inform it not to access the database on postback.
Something like...(pseudoCode)
for (int i = 0 ; i < webpartmanager1.webparts.count ; i++ )
webpart wp = (webpart)webpartmanager1.webpart[i];
if (wp != null)
if (wp.ChromeState == PartChromeState.Minimized)
{
// set a known variable in this particular webpart so it can determine whether to refresh its datagrid or gridview or whatever
}
}
OR
Can a usercontrol webpart determine its own ChromeState ????

Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

I added UserControl Webpart on the site and got this error:
error CS0117: 'ASP._60b6ad6d_6998_4413_8d26_f07e4e897ce8_1417418301' does not contain a definition for 'btnPressMe_Click'
It is very simple user control.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.
A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.
How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?

I have the problem that when i´m adding my usercontrol to my default page the events do not fire. I already know that I had to add the usercontrol as soon as possible to the lifecycle, but I can´t because I know the number of buttons after clicking on my default button.
code:
my default.aspx.cs page
protected override void OnInit(EventArgs e)
{
if (!IsPostBack)
{
addPruefstation aP = (addPruefstation)this.LoadControl("addPruefstation.ascx");
aP.ID = "ucPruefstation";
Session["ucPruefstation"] = aP;
}
base.OnInit(e);
}
protected void bApply_Click(object sender, ImageClickEventArgs e)
{
int anz;
Int32.TryParse(((TextBox)tablePruefstand.FindControl("tbPruefstandstationen")).Text, out anz); //here i´m getting the number of buttons
Session["anzStation"]=anz;
addPruefstation aP = (addPruefstation)Session["ucPruefstation"];
aP.anz = anz;
Session["ucPruefstation"] = aP;
phPruefstation.Controls.Add(aP);
}
my usercontrol.acsx.cs:
public int anz;
protected override void OnInit(EventArgs e)
{
for (int i = 0; i < anz; i++)
{
tcButton=new TableCell();
trPruefstation = new TableRow();
tcEmpty = new TableCell();
tcLabel = new TableCell();
tcTextbox = new TableCell();
tcLabel.Controls.Add(new LiteralControl("Anzahl Leaks"));
tcTextbox.Controls.Add(new TextBox() { ID = "Leak" + i, Text = "0", AutoPostBack = false });
ImageButton imgButton = new ImageButton() { ID = "" + i, ImageUrl = "~/Img/1rightarrow-256.png", Height=15};
imgButton.Click += new ImageClickEventHandler(imgButton_Click);
tcButton.Controls.Add(imgButton);
trPruefstation.Cells.Add(tcEmpty);
trPruefstation.Cells.Add(tcLabel);
trPruefstation.Cells.Add(tcTextbox);
trPruefstation.Cells.Add(tcButton);
tablePruefstation.Rows.Add(trPruefstation);
}
base.OnInit(e);
}
void imgButton_Click(object sender, ImageClickEventArgs e) //this event never be fired
{
throw new NotImplementedException();
}

I am new in sharepoint development. I have 2 webparts attached on a page. The first webpart (MyTestingWebpart1) basically it does only inserting of data and the other webpart (MyTestingWebpart[2]) displays the records from the database. Now my problem is when I try to click on the save button, somehow I don't know how to refresh the webpart that displays the newly inserted record. Is this possible?
I have added a query at the page load event of MyTestingWebPart[2]. Both of the webparts attached are web user controls.

I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn't demonstrate static behaviour?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
' create a new instance of a business object and set a containg variable
Dim BO As New BusinessObject
BO.SomeVariable = "test"
' persist to inproc session
Session("BO") = BO
End If
End Sub
Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click
' retrieve the session variable to a new instance of BusinessObject
Dim BO1 As New BusinessObject
If Not Session("BO") Is Nothing Then BO1 = Session("BO")
' retrieve the session variable to a new instance of BusinessObject...............................

I have a vb class that reads a single row of data from an SQL view. I want to add a property to it that will expose the value of a new bit field. But whatever I do my class always returns the value "false".What am I doing wrong?
Public ReadOnly Property IsPublished() As Boolean
Get
Return valPublished
End Get
End Property
Here's the relevant line from my datareader: Me.valPublished = Convert.ToBoolean(theObjectReader("Authorised"))Authorised is my bit field. I have tried it with and without the "ConvertToBoolean" statement.When I response write the value of the property for rows where this field is true, it always shows false.

I'm building a web system and various clients will have alternate text for default instances throughout the site. One place is the main nav but there are others. The default may be "project" but they may want to call it "event".I'm heading down the road of calling all the terminology settings (there's a list of about 15) and creating an ArrayList that has the id and either the default or their replacement as the items in the ArrayList.I've also got a enum key list called TermKey that has the defaults and the corresponding ID number.
Throughout the code I'll reference TermKey.Project and then do one of these things that I see as options.
1-pull the text from the session (if the client has set it to "event" then the text "event" will be waiting for the call there)2-pull the text from the database every time I need it.3-pull the client's list each time a page loads.Some thoughts on the impact each way or if there is a best practice for

I currently have a repeater control and inside the itemtemplate I have a usercontrol. This usercontrol renders correctly, but I am trying to assign a dataitem to a property in the repeater control.
[code]...
RequestId is just an Int32. It just doesn't assign it.
I can put the eval outside of the usercontrol just in the itemtemplate and it correctly outputs the right id.
If I remove the whole eval and just type a number in then it works fine. I was using an EntityDataSource and this automatically binded to the repeater. It printed out all the information from the database on the screen without any codebehind. But when I put in the code behind Repeater1.DataBind(); it then started to work.
I don't know why, but hey it's solved. It now successfully passes the value through. I imagine it has something to do with the page lifecycle.

I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues;
Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
dynamic c = Page.LoadControl("~/control.ascx");
foreach(var itemin propertyValues)
{
c.item.key = item.value;
}
this obviously doesnt work because item.key is a string and not a property.
