Web Forms :: Get The Backcolor Of Dynamically Created Table Cell?
Oct 19, 2010
I am unable to reterive dynamically created table cells back color which has been changed by the click event of the cell.I am adding table cells dynamically on asp.net page and also setting cells back color. So when the page is loaded, table has number of cells with different colors.Table cells back color can be changed by clicking on it through java script. On page post back event, i am jutst getting those colors which were set before the click event.For example:When the page is loaded, cell1= red and cell2=red.If i click on cell2 then it will change to blue so now cell1= red and cell2 = bluebut on post back i am getting cell1= red and cell2 = red.Table is recreated on post back event.

Im creating a table dynamically in my codebehind to display some statistics. The table is in a usercontrol. When the page first loads, its created and displayed correctly. If I do something that generates a postback, the table subsequently disappears, this is because its created inside a !IsPostback. How can i ensure that the table, once its been generated, stays visble on the page ? I dont want to generate it each time the page loads as it involves a lot of calculations on the database which will slow the pageload down.

In my code I create a table dynamically and I try to restore the table after a postback. But although I recreate the table during the Page_Load event with the same id's before,the table doesn't appear with the same state and values as before.
I think it will be a typically beginner error, but I wasn't be able to locate the error whereas reading different posts and tutorials related to this topic.
//Code behind
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack & _hfsubmittedURL.Value == "tbCreated")
{
TableRow row1 = new TableRow();

I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?

I have an html table with rows and cells. And I have dynamically created a label and would like to assign the label to one of the cells of the table. What I am doing is I have a JavaScript which executes a code behind method and it would not accept an already created asp.net label. So I have created the asp.net label programmatically but cant assign it to the table to display the text value of the label. Below is the code:
[System.Web.Services.WebMethod] public static void EndCandiateTest(){
try { totalTestMarks = ts.RetrieveResults();
grade = tsp.RawScoreAndGrade(totalTestMarks);
remarks = tsp.ScoreInterpretation(totalTestMarks);
testResults = "Raw Score: " + totalTestMarks.ToString() + "
Grade: " + grade + " Remarks: " + remarks;
ts.ShowResults(testResults);
} catch (Exception e) {
} }
protected void ShowResults (string results). I want to display this label in an already existing html table.
messageLabel.Text = results;

I have the following table row on my .aspx page.
[Code]....
I can change the color of the return value based on conditional statements but cannot figure out the correct syntax to change the table cell back ground. My attempt is commented out.
How do I correctly declare the table cell? Findcontrol must not be the correct way.

I'm maintaining a dynamically generated table in ASP.NET, which allows users to move items up and down in the table. What this essentially does behind the scenes is just swaps around the 'sortorder' which the table is sorted by. I have checks to see if a row is the first/last column, and if so only display up/down (whatever's relevant). An issue has crept up now and I have no idea why. For some reason, most of the time (not all of the time strangely) the up and down buttons don't work. Using 'Up' as an example, the current record does get set to the 'above' rows sortorder, but the 'above' row doesn't take the below rows sort order. Now I've set my breakpoints throughout my code, and strangely everything gets set fine. It's just when I call SubmitChanges() to the LINQ data context, that it seems to put the wrong value into the database. Also what's strange is that I think that if you click it again, it actually works. But it doesn't work properly as the number is still out by a bit.
Here's my code:
if (Request.QueryString["dir"] != null) {
if (Request.QueryString["dir"] == "up") {
var currentrecordup = (from s in dc.InvoiceItems
where Request.QueryString["val"] == s.id.ToString()
select s).Single();
int valsortidup = (int)currentrecordup.sortorder;
var prevrecordup = (from s in dc.InvoiceItems
where s.sortorder < valsortidup
orderby s.sortorder descending select s).First();
int prevsortidup = (int)prevrecordup.sortorder; int tempval = valsortidup;
currentrecordup.sortorder = prevsortidup; prevrecordup.sortorder = tempval; }
else if (Request.QueryString["dir"] == "down") {
var currentrecorddown = (from s in dc.InvoiceItems
where Request.QueryString["val"] == s.id.ToString()
select s).Single(); int valsortiddown = (int)currentrecorddown.sortorder;
var nextrecorddown = (from s in dc.InvoiceItems where s.sortorder > valsortiddown
orderby s.sortorder ascending select s).First();
int nextsortiddown = (int)nextrecorddown.sortorder; int tempvaldown = valsortiddown;
currentrecorddown.sortorder = nextsortiddown; nextrecorddown.sortorder = tempvaldown;}
dc.SubmitChanges(); Response.Redirect("EditInvoice.aspx?id=" + Request.QueryString["id"]);
}
The sortorder column in my table is an int field that allows nulls.

On runtime I am creating table structure using javascript and appending it to the div which is placed in an update panel. Problem here is, when I use asp.net button control, onClick of the button it posts the page to server and whatever javascript tables I have created it goes off. When I use html input button (input type="button") I don't face this problem and tables also stay there. But I have to use asp.net button to take necessary actions on the server side. Is there any way that I can restore the structure or use asp.net button control alongwith dynamic javascript.

I created a table dynamically with its row cell contain textbox. Now I need to show a hovermenuextender popup window on each rows textbox. I spend more time for this. But not getting till now.
This is my code for dynamically created table
private void GenerateTable(int colsCount, int rowsCount) {
string qry2 = "select lchannelname,ltransformdata from latestchannel where lenable=1";
DataTable dt = ob.getDetails(qry2);
dt.Columns.Add(new DataColumn("combined", System.Type.GetType("System.String"),
"lchannelname+ ' '+ltransformdata"));
//Create the Table and Add it to the Page
Table table = new Table(); table.ID = "Table1";
Page.Form.Controls.Add(table); int flag=0;
foreach (DataRow dr in dt.Rows) { TableRow row = new TableRow(); row.Width = 200;
TableCell cell = new TableCell(); TextBox tb = new TextBox();
tb.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderWidth = 1; cell.Width = 200; tb.Width = 200;
// tb.ReadOnly = true; tb.Text = dr["combined"].ToString();
tb.ID =flag.ToString(); cell.Controls.Add(tb);
row.Cells.Add(cell); table.Rows.Add(row);
AjaxControlToolkit.HoverMenuExtender hrv = new AjaxControlToolkit.HoverMenuExtender(); hrv.TargetControlID = tb.ID;
Here I am confusing for which way is using for popup panel1
hrv.PopupControlID = Panel1.ID;
hrv.PopupPosition = AjaxControlToolkit.HoverMenuPopupPosition.Right;
Panel1.Controls.Add(hrv); flag++; } }
protected void Page_Load(object sender, EventArgs e) {
int numOfColumns = 1;
int numOfRows = ob.selectLatestEnableCount();
GenerateTable(numOfColumns, numOfRows); }
I want to popup this Panel1 on textbox through hovermenuextender
<asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px">
<div style="border:1px outset white;padding:2px;">
<div><asp:ImageButton ID="ImageButton1" ImageUrl="~/images/close.png" runat="server" /> <asp:LinkButton ID="lnkButtonHide" runat="server" CommandName="Edit" Text="Hide Channel" ForeColor="olivedrab" OnClick="lnkButtonHide_Click1" /> </div>

My problem is that I have an ASPX page which contains an ASP:Table. The rows for the table is added dynamically on Page_Load. One column in the table contains TextBoxes, BUT when I type something on a TextBox and cause a postback, I am unable to find the value just entered. And above that the table is not displayed after the postback.Can anyone help me please? I want to keep the table viewstate with the modified textbox values, so that when i post back to server, I can intercept these new values.

I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
The "making the GridView row display it" part is the one that's giving me a hard time.
What's the best way to do this?

What I need to do is perform some kind of decision statement and when true I need to change the backcolor of a treenode to grey, so that it has a grey box around the whole text. There is no backcolor property for the tree node and I don't need it applied all the time so I don't think a CSS class will do this.

VWD 2008 Express. Visual Basic.
I have a gridview control that has a different background color for alternating rows (done using cssclasses). In the RowDataBound event code, I want to change the background color of a ListBox control in one of the cells to match the row color. I have tried the following (in blue), but it does not seem to work. The listbox control still remains with white background. How may I determine the background color of the row so that I may set the ListBox background to match?
[Code]....
A corollary question is, "How may I programmatically reference an item within a CssClass?" For instance the CssClass is named "datagrid." How do I programatically retrieve the value of "background-color" that is defined in this CssClass?

I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
