Forms Data Controls :: Enable / Disable Controls In Template In Gridview When User Clicks Edit
Mar 4, 2011
I am looking to enable/disable controls (TextBox, DropDownList, etc.) in a GridViews template column based on the users specific access level when the user clicks the edit button. I have tried the following two methods:
Suppose the Gridview on the page is for showing the detail records of the Header master record on the same page. How to disable the "Edit" within the Gridview? I would like to disable the "choose" in the Popup of the Gridview and also to disable any buttons of that.
I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
I'm trying to enable/disable buttons in my gridview according to a value in gridview's field. But everytime when I try to run my page, it shows me below underlined error and point to my gvTimeSheet.DataBind() in page_load.
"Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.GridViewRowEventArgs'." I also tried to enable / disable button in HTML but it just against from what I need it to be.
Example, sheet_status = true, I do not need to enable the button.
I have a gridview that is built based on my objectdatasource.. so at the moment, i have 1 gridview linked to 3 different objectdatasource resultsets.. my question is.. only 1 of the 3 do i want to allow or should i say enable the "GridView1_SelectedIndexChanged" ability.

I have a user control in my Master page and need to be able to Enable/Disable it from ANY page. How is this done? My user control has a few TextBox fields and a button. I was hoping to set a public property and simply Enable/Disable, but public properties seem to only work on the Master page code behind and not other pages.
I'm trying to populate a gridview after the user clicks a button. In the button_click event handler I'm fetching the info I want to display on the grid. this is the code I'm using to do it...
I want a solution for checkbox Check changed.in my gridview when i check on any row it hits check changed event and i have made a button visible if atleast one checkbox is checked.(But when i uncheck i want the button to get hidden if no row is selected).
i am trying to do is set my page up so that when a user clicks on a row in the gridview a hidden checkbox is unchecked... i am new to asp.net but never thought something as simple like this could be so difficult to work out... i've been on it for around 5 weeks now, i started this on my first day of the website, and have actually designed and written the entire site while still trying to work this out... i first did this on the selectedindexchanged event:
Dim cbox As CheckBox = CType(GridView1.Rows(GridView1.SelectedIndex).FindControl("CheckBox1"), CheckBox)
If cbox IsNot Nothing Then
If cbox.Checked = True Then[code]....
problem is the above code throws up errors...! once i take out the where clause it unchecks every checkbox and writes it back... is there a way i can say just uncheck the selectedrow checkbox and update that one row???
i'll admit there are better ways of doing this, and i'm sure the above code is a little messy,
