I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I wrote code of chart with sqldatasource in database column. My problem is I could not able bind. I used DataList Control with a template and literal. Bind literal with <%# Eval("Code") %> But In sql I have ASP.NET tags <% %>. and when processing process %>, it assumes asp.net ends and wrote other text as it is in out put. how to bind this text. Or any other Idea to display graphs from database as per user selection.
I want to get some data from html tags in a web page. For example I have a web site that's got [URL], this is text which I want to split. I want to first URL, First text thats between in first span tags and last text that's between the last span tags.
i need to create a textbox/text area orr any other control for a user to enter some paragraph. He must be able to give colours,formatting like 'bold' 'italics' e.t.c and finally after a busston submission, i need to pass this content to a table inside my database. From database i am sending mails to some users with this content.so this shoulld generate the html tags like <b> <i> e.t.c before sitting in the table How to do this? I am using asp.net 2.0
The pages text are modified and styled with an HTML editor (teleric). The resulting html is stored in a database. The html and style tags are stored with the text ofcourse.
Now, sometimes the HTML tags are DELETED from the text! I realize this has happened first when i see the page text totaly plain on the site. Then i go to the databse and check, and the HTML tags and styling is not there anymore!
The only thing i can think of that could be reason is a method i wrote to search in the text. It strips the texts from html tags so that only the main text will be used when searching for the string that the user has asked for. But the modified texts without HTML tags are not saved to the database. I use LINQ and i never call a SubmitChanges();
i am devalope one webpage it contain one textbox and two listboxes in that user can enter textbox value and select multipule selected values fromlistbox in that how to store database values into one record (i.e database contain 3cloumns in that store in column1:20(textbox value) and clomun2:4,3,5(selected listbox values ) and column3:4,5(selected listbox values)).in that i am using wcf service for inserting method how to pass multipule selected values into services in c
I read data from Excel sheet and I display this data in grid view the problem when I save this data the asp.net tell me that this page contain dangerous code I want solution to this problem but I don't want to enable EnableEventValidation for security reasons.
im using Visual Web Developer Express2005 and language: VB
Example Image of my forum thread that im working:
i encircled in color red the part where i assign the 'content' as you can see above.here EXAMPLE of code in my repeater that populate a <td>(inserting data FROM my database) from my TableField('content')
the part that i encircled in the image above was the data on my tableField named--> 'content'.
The idea was to show not the whole content but to show Only some part of it. example is to show only the 1st 300chars or 100 words.
i tried this code which shows the fist 1-100 chars. [Code]....
Problem is the data i stored in the TableField('content') has other html tagsExample my Tablefield('content') has the following data.
<p class="MsoNormal" style="margin: 0in 0in 0pt"><span style="mso-ansi-language: EN-CA"><span style="font-size: x-small">All hands worked in the preparation..............
When i use the code .tostring.tosubstring(1, 100) it shows: <p class="MsoNormal" style="margin: 0in 0in 0pt"><span style="mso-ansi-language: EN-CA"><span style="font-size: x-small">All hands worked in the preparation..................
instead of starting at: All hands worked in the preparation.......Is there a way that i could extract first the html tags then use the .string.tosubstring(1, 100) to make it work.I use the code below temporarily to generate the 'content' as showed in the image above. i limit the height of the lable to 100px which does the trick. but i know its not a good method thats why im trying to look for other methods.
i'm doing ajax website using PostWebRequest() function, when i call any .aspx page to the target html element the output is coming fine in IE but in FF(FireFox) is coming in html format(html tags) IE output : [URL] FF output : [URL]
Im a PHP programmer and now I'm try to do some work with ASP.NET but I got into trouble just in the first stage of my application.Can Anyone help me find out how to get the user inserted values from CreateUserWizard and insert it to sql database. I have implemented using the following codes, but I keep getting the error message "The name 'identifier' does not exist in the current context". I have tried different approaches but any of them worked.Code:.aspx
I am using SQL data source to display existing records from database as well as adding new records to the database.But in VWD 2008 we can insert only those values which have been inserted into the text box,if I try to change the values or text the Insert option gets disabled.I want to allow user to add only specific field values,for the rest I have created session variables and want to use values from these session variables to be inserted into database.
I want to insert a particular value against a range of dates into my sql server database from the front end using c#.
the table has the column date and worker. so i desire that the user writes the name of the worker and then enters a From and To range into two textboxes so that thorugh a loop function the name of the worker gets written into the table along with the range of chosen dates.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
