C# - Find Dynamically Created Table On Button Click?
Jul 21, 2010
i created dynamically a table with in a function... this table is added to a panel. and this panel is in ajax updatepanel... statically i have given no of rows as 3, for that table... in page_load my table with 3 rows is created.... but i cannot identify this table in another button click event...
i wrote a function to create dynamic table in code behind on selectedindexchanged of checkbox,that is when user will check 2 checkboxex 2 tables will be generated with textboxes,Then on button click i want insert values of these textboxes in database,for that i want to find textbox using findcontrol,but i could not find it,
So i called same function of table creation on page load,but then it shows error that textbox is having duplicate id
My page contains a button [Button1].I've dynamically created a new button [Button2] in the Button1_Click event and and assigned event handler also.But when clicking on Button2, Button2_Click event is not fired.I think its because the page looses dynamically created Button2 after post back, since it is created in Button1_Click event.Is there any way to maintain Button2 on page and raise Button2_Click event ?
I am creating two buttons within the StoryGet() method, first when the page loads. When one of the buttons is pushed, lets say the left one - I want to call another method - "ButtonLeft_Click"
Ive used this same solution in other sites and it worked. With this solution, click event never fires.
If I move the StoryGet() call from Page_Load to PageInit() the button event fires, but because this event also calls StoryGet() the method runs twice, which I don't want.
I tried adding this to page_init so the original StoryGet() method only gets run the first time the page loads unless the method is called directly but then the page loads, but the button click event doesn't run again
if (!this.IsPostBack) { piccount = 0; StoryGet(); }
Their is placeholder inside update panel to which i add my dynamicaly created a div which contain a link button (dynamically created). When i click link button div get disappear and link click event is not fired
im creating a button control in page int and im assing a click event for the button control. here the click event is not firing for the first time. here is my code.
How to create a table in the code behind to display data from the database by creating a new table etc. How I could target existing HTML in my aspx file as opposed to creating a new table in the code behind?
then the database table is created in database(that is SQL express),how can do that.Please sir help me in that problem.I try that thing and debug the code and there is no error in the code but when I click the button in run time ,no table is created in the database(which is placed in sql express 2005).So my problem is that why the table is not created in the database. [code]...
My question is that if the user click on button (which is place in default.aspx, for example) then the database table is created in database (SQL express), how can do that? I have tried but errors are occuring during debugging, errors are:the best overloaded method match for 'system.data.odbc.odbc command.odbc command(string,system.data.odbc.odbc connection)'has some invalid arguments. Argument'2':cannot convert from 'system.data.sqlclient.sqlconnection' to 'system.data.odbc.odbc connection'. The code written in c# behind the button (button is placed in default.aspx, for example) is:
using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; [code]...
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.
i'm using a repeater with an hyperlink and i'm displaying some data from a table x and when the link is clicked i want to add some from the displayed data in another table y..I used a datasource for selecting information , should i use another datasource for the insert command or what to do ..
I am coding online sales a website but I've a problem on main page I have to show products I made it as 4 columns table but there is over than 100 product and i need paging for that. How can I fix it like 20 products per page.
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.
I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.
I am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index) LinkButton lnk = new LinkButton(); //lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid [code]...
I created dynamically a table with 3 rows not by using table tag. I need to find these rows in scripting, in button click, if any of these rows is empty then need to generate an alert message like enter current row.
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> <div> <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="~/images/element_up.png" /> <asp:LinkButton ID="LinkButtonUp" runat="server" CommandName="Cancel" Text="Go Up One Pos" ForeColor="olivedrab" OnClick="LinkButtonUp_Click2"/> </div> <div> <asp:ImageButton ID="ImageButton3" runat="server" ImageUrl="~/images/element_down.png" /><asp:LinkButton ID="lnkButtonDown" runat="server" CommandName="Delete" Text="Go Down One Pos" ForeColor="olivedrab" OnClick="lnkButtonDown_Click1"/> </div> </div> </asp:Panel>
I have created table into database dynamicaly,while inserting records into that dynamic table i faced problem.
The name "STD000001" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. this error occured.
I created dynamic table by ,
declare @STUDENT_Table varchar(50) set @STUDENT_Table = [dbo].[GetStudentTable](@SchoolID) exec (@cmd) [code]....
this stored procedure.....
Should i give any permission while creating dynamic table.
Say for example, I have script like below whereby everything is same except the table name and each table name will append an incremental number, is it possible for me to have a for loop to dynamically add the incremental number?
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.
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?
