Forms Data Controls :: Gridview Find Invisible Row From Code Behind?
Sep 23, 2010
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 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.
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.
regarding gridview Template column.in my template column i have a textbox and i need to invisible to user. but when i set visible property "false" then textbox value is not render.
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:
Dim Application = From AL In db.AnnualLeave _ Where AL.Approval <> True _ Select LeaveID, EmpID, Name GridView3.DataSource = Application GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
I have a gridview control inside an updatepanel. When I run the app and look at the source code generated, there is no source code about gridview. So, I can't aproach to the elements inside the gridview.
My question is, where is rendered code of gridview and how can I approach controls inside it?
I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?Â
I have 2 fields in my gridview one called ScriptType the other BagNo, when a user click the edit button, I would like the BagNo filed to be disabled if the ScriptType field is = "TTA" and enabled otherwise. How can I do this?..something along these lines see below..I am using VB..
I have a query expression which I am binding to a GridView in Page_Load. The data I want to capture in the SelectedIndexChaned event is in a BoundField defined thus:
Visual web developer 2010 express; made a simple web page ( tables and text; that went fine) added a data grid; easily seen in design view, but not there at all in debug.
I am trying to update my Fromview Delete button to Visible = false, if a record in another related table is inhabited.
But I keep getting errors, or it is still visible even though I know that there is not a record.
[Code]....
So here is what happens, First the Gridview sets the pageIndex of the Formview then
I want it to read from the customer_contacts table and if the SelectedValue (LocationID) is in a table ie if there is a contact assigned to this location, I don't want them to be able to delete the location until they have reassigned the contact to a new locationID, and If there is only 1 location on record, they cannot delete either.
I have a formview which contains a question and 5 checkboxes with answers alongside. Some of the questions are true/false so I want to make checkboxes 3, 4, and 5 invisible.
Should this be handled in code-behind? (I don't see any ready-made events for paging through the formview) or is there a way to test data and change the visible property in;
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.
I am trying to make columns of a gridview invisible if they contain a space. The page contains a combo box which users can change. This causes a change in the data in the gridview. I use the following code:
[Code]....
[Code]....
What is working: On the initial page load, the correct columns are deleted. However, if the user changes the combo box, and the gridview has different data loaded into it, it cannot make visible what was previously invisible. I added the ...visible = true line to get round this, but when I load the page, it seems to get locked into a loop forever, and the page never loads - this is why the line is commented out.
This should be soooo simple, but it's making my brain smoke. I've tried writing the results on whether there is a space in the cell to an array, and then using that to make the columns invisible. I've tried doing this in different events, but it always has the same problem.
I suspect that if I can find out how to reference the contents of the gridview from outside its events, it may be easier.
i would like to uncheck a checkbox in my gridview when the user clicks on that row... how do i do that in vb.
also, when trying out my website, when i do uncheck the checkboxs and click on the link to go back to the home page, the gridview on that page which links to the same table does not update the checkboxes with the new values.
I have a GridView in which I want the program to find a specific column, but it doesn't. I've used this code in another program where it worked so what am I missing here? Why doesn't it work? Here's the code where I'm trying to find "status" in column .
i have a gridview and i have made table in gridview and in table i have bound some controlsbut i am unable to find control. if i am not using table in gridview then i am not facing the problem but when i am using table in gridview then i am facing this problem please send me a solution of this problem.
