C# - Cannot Retrieve Textbox Text From Code Behind
Oct 29, 2010
I have a Telerik:RadTextBox control in my markup called txtName. I'm trying to retrieve the inputed value in the code behind with foo = txtName.Text; but var and txtName always show an empty string.
I guess the code couldn't be easier. Basically what's happening is, when I click my 'save' button, there's a postback and the text in the RadTextBox just disappears.
update Found the problem. My web.config file had a different version of the Telerik dll file that was actually in my bin folder.
{ TextBox tb = new TextBox(); tb.TextChanged += Test; } private void Test(object sender, System.EventArgs e) { Label2.Text = "ok"; } When I run this code and change text in tb TextBox, nothing happens.
But I am getting null in the string t_Name everytime irrespective of what is the current Text of txt_Name. However I can get the text if I disable the ViewState for the page.
I have a text box were people will submit a large amoyunt of text to a field in a database. The text is set out multi line in paragraphs with returns. When the text is saved to the database it saves it as a continuous line of text. how do i save and retrieve it with the returns included.
I'm trying to make a dynamic search page, for a table of 121 fields. It'll start by check boxes to check the fields where to search, and check boxes to check the fields in which the results will be shown in. I'm having an issue with taking back values from the text boxes that I add to the page, and I don't know what is the problem.
I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.
I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.

I have a DetailsView Control, inside as a template a TextBox. I need to findout the value for a TextBox when Inserting data Event handler-, _ItemInserting. The script does not work.

I have a C# class from which I would like to access a string contained within a TextBox. The TextBox is defined in a an .ascx file. What headers should I put in the class to be able to access this TextBox string?
I have uploaded some tab-delimited .txt files on my web site (actually run on my computer, ie localhost, for now), and now I try to retrieve the data from those files. I do this by calling a vb file containg the sub below. Everything works great, except that the sub won't recognise unicode characters. I can split the resulting string using vbnewline and vbtab, but already in the sub in question, the string doesn't understand the Swedish letters åäö, apostrophes and more.
Shared Function getTextfile(ByVal FullPath As String, Optional ByRef ErrInfo As String = "") As String Dim strContents As String = "" Dim objReader As StreamReader Try objReader =New StreamReader(FullPath) 'UTF8Encoding? strContents = objReader.ReadToEnd() objReader.Close() ErrInfo = Ex.MessageCatch Ex As Exception End Try Return strContents End Function
Many WebSites where we asked in textbox to enter text for search, such as above you see "Search Entire Site" in this Microsoft ASP.net website page. Once we click inside the textbox the default message vanishes. So tell me how can i do this?
I need to put together an aspx page on which the user specifies a word document. These docs are all in the same format. I need to retrieve text from form fields in the documents and then insert these into a SQL server. I'm completely new to this kind of thing. Can anyone outline the principles behind what I need to do, or point me to a site which will explain it in simple language.
