Forms Data Controls :: Visible / Invisible Panel Inside Gridview
Aug 15, 2010
I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
In the main code, I just have a panel inside a DataList control. I'm attempting to adjust change the visibility to true or false in the code behind, but it's not having any affect on the panel.
I have an asyncfileupload control within a panel control. The panel is initially set to visible=false on page load. After a user clicks a button to display the panel contents however, I set the panel to visible and the user can then use the asyncfileupload. The problem however, is it seems much of the javascript associated with the asyncfileupload, does not function properly when the panel containing the upload control is set from invisible to visible. If I set my panel's "visible" property to "true" initially, then it works fine. My javascript error message is as follows:
"Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent."
Basically within my asyncfileupload control, I have the following line:
[Code]....
In this scenario, my "args" variable is always null (when I set my pane's "visible" property to "true" on page load, the args variable DOES contain data. Any idea why switching a panel from visible=false to visible=true, would cause an error like this?
i have three panels in which panel A has some controls which are mandatory and Panel A by default is visible in the screen . now when i click on save method i am getting the validations messages of Panel A but when i am clicking on panel B Panel A is getting visible = false,
Now i am cliking on SAve method i am not getting a validations message ?
as it is not recognising the controls of a invisible panel.
in a posyback button click event i get the status(condition ) from database by executin query as said earlier currently i have this controls visible true/ false on server side code in posyback button click event after getting the condition but as suggested by u as it takes longer time on server side to makes controls visible true false to do it on client side so in posyback button click event i assigned a hidden control with the condition value now i want to pass this value to client side script so that i can toggel the visiblity depending on hidden control value from posyback button click event i am activating the setype function in client side which has the code as mentioned...wht i need is pass the hidden value to clinet side & make & position the controls on client side.
I have a gridview that is inside an Update panel. The gridview has several linkbuttons in its rows.
Before I put the gridview inside the update panel, when I clicked the 'counter' linkbutton, another
(standard) panel would become visible. Now it doesn't, even though I do get to the gridviewrowcommand event.
This standard panel has a button on it that I want to be the trigger for the update panel.
I have included my code below (content page & codebehind), with non-relevant sections deleted. Note that the script manager is not missing, it's in the master page.
I have a web page that I have a media control player on along with other controls in a table.It's a training video, so the controls are not visible.So the user can advance to the next web page,I thought I would have a button control inside an update panel with a time control so that the user had to watch the video and then the button control would appear after the video completed.I'm setting the button update panel to NOT visible and then turning it one when the time control elapses the same amount of time that the video runs.My problem is that when I set the visible property of the update panel to NOT visible it also makes the media player's panel NOT visible too.They are in two different panels.The medial player in a standard panel and the timer control connected witha separate panel that contains the button for the user to proceed. When I set the visible property to "true" the media player runs but the update panel with the button is visible also.

This is the code for the update panel and continue button that is in a separate table cell.I even split the table and so this is in a completely separate table but I still get the same behavior.
my page contains gridviews, textboxes, comboboxes... : one of the gridview is hidden; the user needs to press a button to make it visible (it is inside a panel that contains a vertical scroll, and have a header and a footer, and this last panel is contained in an update panel).
i want to make the header and footer fixed while scrolling. i need this to work in ie and in firefox the latest versions.
I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
This is my treeview code. when i enter through orderentryhome page i want to invisible savedordermenu and checkout menu. If i click submit button in organizationdetails.aspx page then savedordermenu and checkoutmenu will diaplay along with other menus. This is my requirement.
I have a Data Bound DropDownList and a Panel in a step of the CreateUserWizard. I would like to make the panel visible based on the selected value of the DropDownList.
Here is my code that is not working. Any help identifying what I missed is appreciated. (Yes Post Back is enabled on the DropDownList.
I have a gridview Control. In that control I need to show the headers when gridview is scrolling verticall. I tried your post from here [URL].... It's working in page loads.When I try to click any other buttons it's not working(it's showing all the records. I mean It's not scrolling). I have Add, Delete and reset buttons.
protected void FormView1_ItemInserted(object sender, FormViewInsertedEventArgs e) { // Here I want to make a label "Saved" visible after user inserts the record into the formview. // the label is in InsertItemTemplate of the formview next to Insert and Cancel Links. It is invisible by default. // Is this the right event that i am in to do something like this.. if there is any other way to do this, }
I'm trying to make my TD visible or not inside a repeater. I keep getting an error "Object reference not set to an instance of an object". here is my code:
[Code]....
and my code behind:
[Code]....
I know it has something to do with how my findcontrol code is written, but I can't figure it out.
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
let me explain completly. I designed an gridview, header template i added one textbox and button if the user enter something on Txtbox and click button then based on input i show corresponding rows only, all other rowss will be hidded using Javascript like below
tblOrders.rows[CurrRow].style.display = 'none';
now im doing something on the Gridview_RowCommand event at this time the gridview got refreshed so that the hiden rows are visible, but i dont want to show the hidden(invisible) rows while rowcommand event fired.
I have a gridview that is being populated off of a query that has joins in it. It works fine. However, I want to display one record of all information but then blank out all colunmns accept 1 for the other 3 records that it is picking up. In other words, right now, all three records have duplicate info in them accept this one column. can this be done? Can I somehow blank out other columns based upon what is in the single column? This is all being done in a gridview. I realize it would do a master detail type scenario but I want all of this information to display without someone having to click on a field or anything.
I've run into this before, but I was using a formsview and just changed the field to hidden. I am trying to get the value of a cell out of a gridview to a variable and here is the code:
[Code]....
This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null. Changing it back to visible and it works.
I'm not sure why the visiblity of a control changes the functionality of it.
