View 4 Repliesi want to access the child datagrid controls from parent datagrid command event.
View 4 RepliesI have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
i have one grid and one button when i click on that button then it expand and showing another grid under the row of parent grid how to do that.
View 2 RepliesI have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
[Code]....
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
Is this a known change or a bug of ASP.Net 4.0?
i have one parent grid on which if user clicks a record ,the child details should get displayed on same page.
for example :
There is one department details table and employees table:
if user selects a record in department details grid,then employees in the selected department should get displayed in the next grid in the same page
I have a main MasterPage that, as intended, forms the entire layout of my site. It has a bunch of methods common to all pages that use the mastertype, such as EnsureLoggedIn and such.
I want to move on to using nested masterpages to open up better layout options in some of the pages, but I am running into an issue. I get the layout of the nested masterpages fine, but I cannot access any methods in the parent masterpage.
I know my explanation seems a little sparse; I'm not exactly sure how to word what I'm looking for, heh. But here's a short example:
[Code]....
If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.
I am using a collapsible child gridview inside a parent gridview. When I click on the expand image, the data to displayed is put up correctly, however when I make some changes in the child gridview, they seem to be lost!! That is, the changes do not get reflected in the database.
View 3 RepliesI have created a search page for web application that will allow a user to search the database based upon employee name or supervisor name. It is a multiple table database that is linked together by an unique employee number column, primary key in people and foreign key in supervisor. I have a parent/ child datalist used to display the record. When searching by the employee name it will return the record correctly if there is a record found. However, if I search by supervisor name and there is no match for the supervisor name, it will return all the records and create the parent datalist with all the employee details there, but the child datalist with the supervisor information is not display as there is no record with that supervisor name.

I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
Date1 ProjectCode1 Hours ApproveChkBox
Date1 ProjectCode2 Hours ApproveChkBox
Date1 ProjectCode3 Hours ApproveChkBox
Date2 ProjectCode1 Hours ApproveChkBox
...
I would like to be able to display the information like:

Is there anyway to do this using a nested gridview? Or is there a proper way to display this type of format?

Now, my problem is i have a heirarchical Grid so i need above functionality in the child Grid...
I have parent form in which i have two buttons. button1 and button2. By clicking on button1 a model popup widow shows. In popup window i have a button like button3 what i need that by cliking on button3 on popup page i want to fire button2 event on parent page and close popup page.
View 1 RepliesI have a listview that has n rows.
Within the EditItemTemplate and InsertItemTemplate I have a cell that has a textbox and a button.
When the button is clicked a popup window is shown, where the user can upload a picture. The name of the uploaded picture is retrieved.
Now I want to send that picture name back to the textbox within the listviews EditItemTemplate or/and InsertItemTemplate (that is ofcourse one at a time depending on what the user is doing, inserting or editing a row).
The code I have written so far looks like this. The below code has been abbreviated
[Code]....
The code behind looks like this (also abbreviated). Actually I don't think the code behind is needed, since its mainly javascript from the popup window (child page), but nevertheless here it goes.
[Code]....
And at last the child page / popup page.
Well there is not anything to see here, cause I'm using the Telerik RAD upload control, which is doing everything for me.
However the line below may be of interest. Here I'm taking the name of the uploaded file (picture) and printing it to a label.

I am working in Asp.net 4.5. I need to create a grid as like below, I am struggling to make the merging cells and make it as multi header row by combining all the cells...
Is there any sample to make gridview like this.... I need to do this on codebehind. I browse through the internet and found couple of sample but those are not having the header like i posted. I am little confused about making full header as merged cells....
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'.
In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I tried
<%# DataBinder.Eval(Container.DataItem, "_comments_Replies.childcomment")
Same as above error came to me.

View 2 RepliesI have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.
'*******************************************************************
The user control is being referenced from the web.config file ** Works find! **
[Code]....
EDIT.ASPX Page **-- WORKS FINE!** [Code]....
I would like to ask if there is any control act like grid to display records.The 'datasource' will be a customed class, this dataclass has List<T>, so I will populate each element by iteration into the grid.Any control can I use to work like a grid?The number of records will around 100.This control should also allow the user to select a record.
