Forms Data Controls :: How To Access Dataobject Of Parent Gridview Control From Nested Gridvew
May 10, 2010
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
i have a parent gridview,It has child gridview in every row.The edit and delete event of this child is working is fine.When i add data to through child gridview with empty data template.i can 't find the value of the parent contril id.
gvProductFeatures is the chid gridview... protected void gvProductFeatures_RowCommand(object sender, GridViewCommandEventArgs e) { try { if (e.CommandName.Equals("EmptyAddNewFeature")) { GridView gv = (GridView)sender; if (gv != null) { // here i need find the appropriate control id from parent..how?? int intIndex = Convert.ToInt32(e.CommandArgument); Label lblEmptyGroupPK = (Label)gv.Controls[0].Controls[0].FindControl("lblEmptyGroupPK"); TextBox txtEmptyFeatures = (TextBox)gv.Controls[0].Controls[0].FindControl("txtEmptyFeatures"); } } } catch(Expection ex) { } }
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.
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 a login control and at is nested 2 deep in a header control i.e Page --> Header Control --> Login Control. I cannot get a reference to the control on the page using FindControl. I want to be able to set the visible property of the control like
[code]....
I ended up using a recursive FindControl method to find the nested control.
I have a Parent gridview with a nested gridview. Edit on the parent works fine. On the nested child gridview, when I click the edit button, the line goes into edit mode, but the parent row collapses. To correct I added javascript to call the javascript function that is used to expand and collapse the rows. It is located in the RowDataBound event of the parent gridview.
Based on the code samples I have, the way the process should work when the edit button is clicked is the RowCommand and then the RowEditing events for the child gridview are supposed to fire, followed by the RowDataBound for the parent. The child events are firing after the parent though. This wouldn't be a problem except that I am retrieving the parent line that holds the child record being edited so that value can be fed to the javascript function to expand the row. How can I fix this or work around it?
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 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 have a RadioButtonList control inside of a nested ListView control InsertTemplate. I need a way to access this control in the nestedListView_ItemInserting method.
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.
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.
So I've got two listviews; one nested inside the other. The parent is being bound to a collection of objects that contain fields such as MaxPrice, MinPrice, and SuggestedProducts. The nested one is being bound to the SuggestedProducts collection of the parent item. How could I reference MaxPrice and MinPrice in the nested listview? Is it even possible? If you need any clarification, leave me a comment and I'll update my question.
I have followed your Nested level gridview and found it working, but i want add a button in the child element(from your example i will have a btn in Product grid and it should get contact_id (parent datakey value as well) ),as i need to update in database.
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
I have created a gridview (this is a usercontrol) with another gridview (also a usercontrol) inside it. Now I would like to bind a checkboxlist to the inner gridview. This is my markup for the inner gridview user control
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 user controlThe user selects some items from user control (check box list)User clicks update button on user control The new rows get updated on a gridview on calling page & user control is hidden
a)I have made the user control but I dont know how to return the results and bind them with gridview on my calling page.
b) Update: If I create the update button outside the user control and on my calling page and then on its button click event Isomehow access user control checkbox list selected items would that be a good approach ? And how to do this stuff ?
