Web Forms :: When Check The Checkbox Then Only The Textbox Need To Be Enabled?
Apr 5, 2010
I am having a .aspx page which contains a checkbox,a button and atextbox which is in disable mode.When I check the checkbox then only the textbox need to be enabled.And after enabling if the textbox is empty and when clicked on the button an error msg should be displayed like "Textbox cannot be left empty"and this should be done dynamically.I dont want to add the requiredfield validator during design time instead I want to generate the required field validator when the button is clicked and msg to be displayed.
I have a radiobutton and if it is checked "Yes", then the three textboxes that are disabled in default will be enable. Now that this textboxes are enabled I want this to be mandatory. How could I do this via javascript or code behind? If I do it in code behind then autopostback is need which is unnecessary.
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
There are tons of references for this error message on the Web, but I can't figure it out. The problem is that the application works fine when I run it locally or when deployed to other servers. There is just one server where I get this error during a post back from an Update panel (it is supposed to populate and open a popup panel). There is no Response.Write() anywhere in the code and the other either. I think. The next thing I will try is install the remote debugger. In the meantime, can someone tell me how to check if server trace is enabled (IIS 6)?
My only requirement is to find a selected pdf in a folder is Reader enabled or not, more specifically if usage rights are defined in a way that allows people to add annotations (e.g. comments).
I am doing this in windows application. If I click a button, an event is triggered searching a folder for PDF files. This event needs to check whether or not the PDFs in the folder are Reader enabled for comments. If they are, I need to remove the comment usage rights or revert the PDF back to its original version.
My code can only find PDF files in the folder. I don`t know how to check if the selected PDF is comment enabled or not.
private void button1_Click(object sender, EventArgs e) { { string[] filePaths = Directory.GetFiles("D:myfolderpdffolder"); List<ListViewItem> files = new List<ListViewItem>(); foreach (string filePath in filePaths) { ---need to check comment enabled or not--- } } }
I want to create a custom attribute to check if the browser has cookies and javascript enabled. I'm guessing I would create a ActionFilterAttribute that would redirect to a controller action to load a page to check cookies and javascript on the client side. If they are enabled then it would redirect to the desired action, otherwise display an error message. Is this a correct approach or is there a better way to do this?
I have the following issue. I am displaying a lot of models from the database. Next to each model name there is a checkbox. So a customer can check as many check box as he wants and when they click on the save button, it gets saved to a table in the database.
I have written the whole code in the code behind. (.cs). But I am having dificulty capturing the check box checked and how can I do it? Here is my partial code:
strLoadCategory +=
"<td>" + dvModels[modct]["Model_Name"].tostring() + "</td><td valign='top' align='left'>" + "<input type='checkbox' value='" + dvModels[modct]["product_id"].ToString() + "' id='" + dvModels[modct]["product_id"].ToString() + "' name='SaveCheck'></td></tr>"; THe number of models is dynamic based on a portal name user selects from a drop down list before this.
if i change the code and put checkbox between the <td> tag. when i click the save button, how can i check the ticked checkbox and get the value of the CHECKBOX_1 in cs?

I have a master/detail scheme for editing an asp:GridView using an asp:DetailsView. One of my fields is for a phone number of type int64 (always 10 digits). I would like this field to always be displayed as (###)###-####. My issue is the first digit in the phone number is always truncated for my edit item field which I used a MaskedEditExtender to achieve the formatting.
When my details view is displayed for editing, the text box displays(_23)456-7890 for the integer 1234567890. Also worth noting that if the property MaskType="Number" is removed, the textbox shows:
(234)567-890_. I would of course have the textbox show (123)-546-67890 after binding.
I was trying to find out if there are any check boxes checked in the datagrid, if non of them is checked it should show me an alert to select atleast one.
My problem starts when there is paging in datagrid...
not able to check the entire datagrid at a time in itemDataBound event for the checked check boxes.
Im using the following code to get the gridview rows that are checked and then add the values to the database.Its all works correctly unless apart from when i check the row at the top of the gridview where when i check the checkbox it doesnt even change to checked so i cannot add that row into the database.
<asp:TemplateField HeaderText="Approval" Visible="false"> <InsertItemTemplate> <asp:CheckBox ID="Approved" runat="server"/>This must be checked to allow the insert. </InsertItemTemplate>
I have a datagrid which is bound to a stored procedure in the code behind. This works fine. But the datagrid contains a checkbox which I need to be default checked. First I didn't bind the checkbox and just used:
I have a field "Active" which can contain either 1 or 0. In the aspx form, I am displaying it in a checkbox in gridview. If the database value is 1, I should have the checkbox as checked, otherwise it should be unchecked. How can this be done.
