Forms Data Controls :: How To Access The Properties Of The Inner Gridview Of A Nested Gridview
Oct 28, 2010
I have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:
[code]....
In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?
I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries
In datalist, I hve populated Grdiview according the Category Id. Inside Gridview , I hve checkboxes. Now i want to get the selected checkboxes names to be insrted into the database. how to get access of those checkboxes inside of Gridview.
Is it possible to access textbox text properties from codebehind when gridview is edit mode? for example I can access label's text properties on gridview row databound event.
[Code]....
So I do not like use Text='<%#Eval("ColumnName")%' this method. I want to manage textbox text properties dynamcily codebehind when click the edit button on gridview. When I clik the edit button these code blocks runs
[Code]....
but rowdatabound event fires again and couldn't find label control. It looks for textbox control to bind data but I can not manage this step.
I have parent gridview5 and nested child gridview6 within it. The page is working as expected and formatted as i need it now.. I added a select button to the child gridview6 and when i click on it i get an error: {"Object reference not set to an instance of an object."}
I found examples of using the find control, but within the parent gridview.. and i use that fine with other controls.. but cant figure out the right combination of finding the selected row for the nested gridview so that i can display a modalpopup.
I have a parent gridview control and a another gridvew control inside parent gridview.I want to access a column named type in parent gridview inside child gridview.And use the value of that column in a javascript function
In nested gridview, i am finding some problem, i want to show child Grid headers in Parent Gridview. Can anyone tell me that how it is possible? Its very urgent. Waiting for quick response.
In Nested Grid, we get a '+' sign. The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.
Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:
I have a nested gridview (gridview within gridview) that I need to render beneath the outer gridview.
I keep finding examples online of showing a nested gridview in the last column of the outer gridview but I need to show my nested gridview instead under the outer gridview.
I was certain that I had done this before by putting a row (<TR>) inside the TemplateField so that the nested gridview would display under the outer gridview. I am getting the data ok for the nested gridview, that is not a problem. The only issue I am having is making the inner gridview display under the outer gridview.
btw, the error is below:
<ERROR>
Type 'System.Web.UI.WebControls.TemplateField' does not have a public property named 'tr'.
I have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)
If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.
[code]....
I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:
Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
I have designed a collapsible nested gridview project using this article as a reference Collapsible Nested GridView with Paging using ASP.Net. I am trying to modify the code to collapse a gridview when another gridview is expanded so that only one nested gridview will be open at a time.
URL....When the user creates a new child record (2nd gridview) how can I ibsert a field from the parent level (obviously from the line where they clicked from).
I have a gridview (gvNested) nested inside another gridview (gvParent). I want to get the selected value of the nested gridview, but keep getting the classic 'object reference not set to an instance' error. I thought that this would work
[Code]....
Where gv.SelectedValue would return the information I needed.
i'm new on this forum and my english is not the best, so i hope that i can explain my problemI have a gridview nested in a Repeater, this is the markup :
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
