Forms Data Controls :: Process BBCode After Control Is Filled?
Jan 23, 2010
I'm having major performance issues with my BBCode/Commenting system. It's taking 3 seconds to process the code, with 5 comments and a simple [b] command.
So here's what I am doing (it's done like this because of the way my backend system is designed):
"LoadComments" function is called with referenced to the repeater. "PagingSystem" is initializedBind data to controlData is pulled from the binded control (if bbcode is enabled) Data is put into a dataview
Process text and convert BBcode (update row) BindData I disabled every feature, including the BBCode, and it's still loading slow. This is the ONLY thing I can think of causing the issue. Here is the base code that process bb:
[Code]....
As you can see, it uses my own data management code. Even without using it, I'm still not 100% sure how to modify the contents inside of a repeater. I don't see how modifying them could slow it down so bad..
I have a details view on my page that has a template field in it. In the template field is a button that when clicked, sets the visible property of another field to true. When this happens the whole detailsview resets and anything that was entered into other fiields is cleared. Is there any way to prevent the other fields from being cleared when the hidden field is set to be shown.
What I have is a datatable being constructed from Sharepoint API. We dont need to worry about the sharepoint api.The code where it fills the data is as follows
Datatable dt = new datatable(); Sharepoint.fill(dt);
Write what I want is as the dt is being filled is to create another column called full path which has a formula col1+col2I dont want to do a for next loop after the dt is filled . very slow !
I have a problem i just cant get around...I'm trying to sort the contents of a gridview that gets filled from a List<T>.
(working in DAL, BLL & Presentation layers).
The Gridview's source code:
[code]....
What i cant figure out is how to implement the sort method to the gridview when fetching data from a generic list... I have been Googling my a** of trying to solve this.
i've 4 similar dropdowns in my form in four different categories, is there any way to bind one of them so that the remaining dropdowns can be automatically filled or binded with the same content as first dropdown
I'm using a DataSet to fill my gridview. The dataset contains several columns, like: direction - fromNumber - toNumberThe column direction can contain the values "incoming" or "outgoing". In my gridview, I would like to show only 2 columns, direction and from/to. If direction = "incoming", the values from fromNumber has to be inserted in "from/to". If direction = "outgoing", the values from toNumber has to be inserted in "from/to".I know I can use a TemplateField to show different text values in a column...But I have no idea how to do this when I want to show the values from a column...
I have grid view that be filled using code behind , and it be displayed with the default pagingmy problem is I want to add two label behind and after the paging links and fill them with certain text such this example
In my gridview,the first 5 columns are filled with the values retrived from database on selecting an item dropdown.The last i.e, 6th column(date) is filled with value given in the textbox.
Now I need to export the gridview rows to Excel in which checkbox is checked.But Now With the code i have,Excel is containing the empty date column.Pls correct my code to get the proper filled Excel.
I have confusion, how can i retrieve value from database and show it in dropdownlist because valuse is store in various field with some are blank means null value, I want to display only fields with some have data . i am doing like this but what to mention in "valuefield and textfield" and how to implement.
con.Open(); OleDbCommand cmd1 = new OleDbCommand("select Restaurant,Parking,Facilities_for_Disabled,Room_Service,Bar_Pub,Fitness_Center_Gym,Swimming_Pool,Spa,Conferen
With the code i have below i am able to export only one page of gridview to excel. check and modify it once.so that i can import all the pages of gridview to excel at a time with checked status of checkbox.
protected void btnExporttoExcel_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[5] { new DataColumn("Presentees"), new DataColumn("StudentName"), new DataColumn("ColgRegisterNum"), new DataColumn("CollegeName"), new DataColumn("Date"), }); foreach (GridViewRow row in gvStdntDetails.Rows)
I tried to use a DropDown-Control (WebDropdown from Infragistics) for the following function: Let the user enter any text or if he wishes choosing by a context menu two different "Already exist entries" in the DropDown-List from where he can choose a value. The behaviour should be this for the DropDown: Right-clicking on the DropDown-Control, filling the DropDownList in the server depending on the choosen context menu item, opening the DropDownList in the client.
The way I tried to solve:
Open (by javascript) a context menu by right clicking on the control
[Code]....
What's the problem? The problem is, that the above javascript function does find the WebDropDown1 control only if it is called client side (e.g. with a OnClientClick button event), calling it from server side (as in the ContextMenu_ItemClick subroutine) it does not find the WebDropDown1 control. The error is shown (translated into english): run time error: object expected.
Maybe a completly different solution is necessary as I transfer a windows forms program into a web form ajax style program. I could use a textbox with dropdownextender for example. But the problem seems to be always the same: uncoupling the dropdown function, which is a client side one, by first filling the dropdownlist on server side, and then invoking the dropdown event makes the problem.
Is there a way for a user to partially fill out a form and not commit it to the database, leave the page and come back to it and the information that the user filled out is still there?
I have a datagrid which retrieves particular columns from an SQL database table. I also have a checkbox appended on to each row, so that selections can be made against rows of the users choice (i.e. select photos to add to favorites).
How can I code this (in VB.NET) so that these checkboxes are processed sequentially? I have heard an "array" might be best for this, but don't know how to code it. Essentially, I want the VB.NET to look through the datagrid list and to process only those rows with checkboxes checked, by applying some SQL based on these selections.
the porblem is that these APIs are feeding thousands of records, so each time i'm paging a new page_index i have to go through all ofl the above steps (1, 2 and 3)this procedure is taking a lot of time
I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:
FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read); BinaryReader reader = new BinaryReader(fsr); byte[] bytes = new byte[fsr.Length]; reader.Read(bytes, 0, bytes.Length); FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write); BinaryWriter writer = new BinaryWriter(fsw); writer.Write(bytes, 0, bytes.Length); // clean up writer.Flush(); writer.Close(); writer = null; fsw.Close(); fsw.Dispose(); fsw = null; reader.Close(); reader = null; fsr.Close(); fsr.Dispose(); fsr = null; Later after sending the email I: mailMessage.Dispose(); mailMessage = null; foreach (string fileName in attachments) { if (File.Exists(fileName)) File.Delete(fileName); }
The error occurs at: the File.Delete(fileName);
how I can delete or reopen these files after sending the email?
I have a project that uses the same form on 5 different dynamic pages. The form will be in an updatepanel (I have no problems with that). My question is how can I populate the form with data and process the data on a centralized class? This form has about 80 controls on it.
I work in VB.
I've given up on trying to programatically generating/injecting the updatepanel/table into the contentplaceholder. (I got it to work but I could not read ANY of the fields even using nested FindControls). So now I've backed up to 5 instances of the form in easy to use UpdatePanels. But I cannot justify writing 5 identical form processor code blocks in 5 different classes.
My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e) {if (!IsPostBack) // if this is the first time page loads, set k to 1 { lognewuser(); }}
I have some field in datadase which is filled through checkboxlist , only selected checkbox has save to fields otherwise they remain blank: My problem is I want to show only filled value in label text using ";" , but when i am going to display it id display like:
I'm attempting to create a update form that will pull information from my database. I'm a little confused on how to get the information into the textboxes on my form. First I have my form:
[Code]....
This is where I'm getting stuck. I'm not certain what code I need or if what I have is correct. Is there an example what my next step(s) are? I would think that I need to set a variable to hold the data, maybe something like txtRace = Trim(GetString(0)???
I'm using asp.NET MVC, and am looking at the JQuery autocomplete plugin for what I want to do. I need some extra functionality that I don't think it provides.
I have a page with two text fields, First and Last name. Ideally, when someone begins typing into either, I would like autocomplete to display both the first and last name of all matches. If one of these matches were selected, I would like only the appropriate (first/last) name to go into the current field, while the other field is also filled in with the appropriate name.
So the problems here are that A) I would like the suggestion text to be different from the value that would be filled into the current field, and B) I would like to update multiple fields from a single autocomplete. Does this make sense? It seems to be difficult to find information on this situation on the net.
What is the trick to get the controls inside the FormView. I was getting them with FindControl() but, now i cant get access on them. Example: i have some ImageButton on the FooterTemplate, great i can get those smoothly, when it comes to the controls inside the FormView!!! null every control. Do you think i should name them differently in every template? This gets me thinking about the table causing this noise. I'm using the DataBound Event and checking for specific Mode! [UPDATED] This is working
