I have a webform with textbox and button,i want to disable the button when nothing is entered into textbox and if something is entered the button must be enabled.How to do it without javascript?
I am using template field in a Gridview. I have a button in that. I also have a method which returns bool. Now I want to disable the button in the gridview if my method returns true. And enable the button if my method retuns false.
I have a grid control where i am binding list of stickers. On the above of grid , that is out side grid i have two buttons Create Sticker and Void Sticker. Sticker basically have three properties Active , Void and Expired displayed as text in column. There is condition of adding only one sticker at a time. Also if there is an active sticker then user cannot add another sticker until and unless its is expired or void.
So what i want is that whenever my grid is loaded if there is an column with text active the the create / add sticker will get disabled and void will get enabled. I am using the folloing code
/// <summary> /// Handles the RowDataBound event of the gvSticker control. /// </summary> /// <param name="sender">The source of the event.</param> /// <param name="e">The <see cref="System.Web.UI.WebControls.GridViewRowEventArgs"/> instance containing the event data.</param> /// <remarks></remarks> protected void gvSticker_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { if (Session["FisherId"] != null) { if (e.Row.RowType == DataControlRowType.DataRow)
I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.
But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.
I am trying to create a button to enable / disable a bunch of code.I would like to use the same button. In the first ''click'' i would like to enable the code (i.e. Play sound file) and in the second "click" to disable the code (i.e. Stop sound file)How can I do that?

I want to be able to change the fields to readonly if a field in the database for the user says they should have readonly access. I can't seem to find the level to go to in order to loop through the controls of the page to set their access to readonly.
