I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?

How do i assign a file path to fileupload control after postback.
I have a simple user control which toggles between the visibility of a few images depending on the UserId. When the page is loaded for the first time, the userID is being assigned correctly (I'm debugging). However, there are two other buttons on the page for filtering the type of users, they are perform their functionality via Ajax (not the toolkit, but the normal javascript ajax) When one of these buttons are clicked, the user control cant get the userid, it always comes up as Zero. Oh, btw, the usercontrol is in a DataRepeater, so it occurs for each of the user.. all the time.. or thats the Idea. I have several other pages like this, (none of them have ajax) and the user control has no problems whatsoever.
My User control code:
[Code]....
And the Data Repeater is something like this:
[Code]....
Here, Immediately after the userControl <ucAB:....> line, I am printing the userid just to see if its valid (by <%# Eval("UserId") %> and the user id's are valid too. I dont understand why the User Control cant pick it up on ajax postback?
I have a main web page and added a user control inside it. The user control has some textboxes. The problem I have is when I populate the textboxes with the data that is in the DB, they do not show the values. The strange thing is If I change the property of textboxes ReadOnly to TRUE, they show the values. The problem is that I need them to be ReadOnly=FALSE.
I am uploading an excel file ( containing int values )using the fileupload control. I need to work on one entire column in the excel sheet.I want to copy contents of the file either in an array or a table and then work on it.Can anybody suggest a better way of working on the excel since .
How to get data (read file) chosen in FileUpload control without FileUpload.SaveAs Method on the server? Is it possible write it at once to some object?
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
I have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.
I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.

In my controller have a FormViewModel which inherits from a domain class declared in dbml. In the constructor of the FormViewModel I want to do a shorthand assignment to the inherited class properties with the passed in object (ie thisPerson) without iterating through each property of the inherited class and assigning its value with corresponding property in the passing in object. Should I use super, base, this, or something else?
I am looking to cache a dataset and then filter the results as they will be used repeatedly. However, I don't know how to assign values in the filtered dataset to variables in C#. I have looked on the internet for the past few hours but all I can get in binding the dataset to a control.
