I have a listview with a nested gridview. I'm having trouble accessing the gridview. I want the gridview to be filled and displayed when a linkbutton is clicked on the listview. I use FindControl to get linkbutton - but cannot get it to work for the nested gridview. I have gridview working outside the listview, but it fails when nested.
Snippet:
asp.net Code:
<asp:ListView> ...............
<SelectedItemTemplate>
<tr >
<td>
<asp:Label ID="BuildingLabel" runat="server" Text='<%# Eval("Building") %>' CommandName="Select"/>
</td>
<td>
<asp:Label ID="AreaOccupied_m2Label" runat="server"
Text='<%# Eval("[AreaOccupied m2]") %>' />
</td>
</tr>
<tr><td colspan = "2">
</td> </tr>
<tr><td colspan = "2"> <asp:Panel ID="pnlInnerGrid" runat="server">
<asp:GridView ID="GridViewBlocksInner" runat="server">
</asp:GridView>
</asp:Panel></td></tr>
</SelectedItemTemplate>
</asp:ListView>

I have a problem i just cant get around...I'm trying to sort the contents of a gridview that gets filled from a List<T>.
(working in DAL, BLL & Presentation layers).
The Gridview's source code:
[code]....
What i cant figure out is how to implement the sort method to the gridview when fetching data from a generic list... I have been Googling my a** of trying to solve this.
I have grid view that be filled using code behind , and it be displayed with the default pagingmy problem is I want to add two label behind and after the paging links and fill them with certain text such this example
I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?
protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e) { int UserID;
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 am using asp.net 3.5. I filled dropdown list in javascript using ajax service but unable to get its selected value in button click event on server side.
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.
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.
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.
This question is asked in Technical interview. I was asked to list controls which will display same way in all browsers(IE, Safari, FirFox) without any problems(rendering, positioning.. etc.)
I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?
With the code i have below i am able to export only one page of gridview to excel. check and modify it once.so that i can import all the pages of gridview to excel at a time with checked status of checkbox.
protected void btnExporttoExcel_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[5] { new DataColumn("Presentees"), new DataColumn("StudentName"), new DataColumn("ColgRegisterNum"), new DataColumn("CollegeName"), new DataColumn("Date"), }); foreach (GridViewRow row in gvStdntDetails.Rows)
I'm using a DataSet to fill my gridview. The dataset contains several columns, like: direction - fromNumber - toNumberThe column direction can contain the values "incoming" or "outgoing". In my gridview, I would like to show only 2 columns, direction and from/to. If direction = "incoming", the values from fromNumber has to be inserted in "from/to". If direction = "outgoing", the values from toNumber has to be inserted in "from/to".I know I can use a TemplateField to show different text values in a column...But I have no idea how to do this when I want to show the values from a column...
I have an AutoCompleteExtender control tied to a textbox. If the user starts typing in it, a drop down pops up displaying the a list with the matching suggestions. If, while the list is being displayed, the user hits the Tab key, the textbox loses focus and its value gets overwritten with whatever choice was highlighted in the list.
The problem is when the user clicks outside the list, I want to achieve the same behavior. It currently keeps whatever the user had typed (before the choice list pops up), but I would like for the textbox to get the value of the last highlighted choice (just as if they hit Tab).
I'm able to capture the event, when the user clicks outside the list, but I can't seem to find how to get to the highlighted value from the choice list.
where each entry has some HTML text and an associated Name and ID.
What I want to do in ASP.net C# is to list each of these entries on a page in such a way that the HTML text should be displayed exactly how it is meant to be (e.g. <b>test</b> should show 'test' in bold) and each entry should be editable. When the Edit button is clicked on an entry, the HTML text should be replaced by a textbox with the text inside it so that you can edit it and save it.
For example:
FOOTER --EditButton--
TEXT test
Now I am not sure on what is the best way to do this. Should I use a repeater with an ItemTemplate for each entry? If I use a repeater, and an edit button is clicked, how do I know which edit button is clicked and how do I know which textbox to display the text etc?
Here Group# and item# are checkboxes. Does anyone know how to do this in asp.net. I am getting data from DataSet. One limitation is that I am not allowed to use third party tool/controls or jQuery.
i have list view and inside lisetview i have another list vie like nested listview lv1 --> lv2 and inside lv2 i have button when i'll click buttion than insert template show but how can fine control lv2 ....? there is my code Lv1 is working but lv2 is creating problem..?
I have a listview that is displaying records currently based on a dropdown.. works great.. now, within those results returned, i would like to filter down some more.. How can i add a dropdownlist to the page that is populated with data from the listview(only 1 field would be used to create the list ) and if you chose to filter by that drop down, then the listview is revised to display only records with the selected value.
Example..
Currently you pick from a drop down.. Report#1, Report#2 or Report#3 Say report#1 returns 100 records.. and the field im going to be filtering on is my "Vendor" field.. so once my listview displays my results, a dropdownlist is populated with all the vendors that were returned with the query.. could just be a few..
Now you are sitting there paging thru all the records.. and realize you really just need to see out of the 100 records, records that belong to Vendor#3, so you pick #3 from the drop downlist and the procedure is called again now filtering on that vendor..
I have two listviews. The inner listview (InnerListView1) is in the SelecttItemTemplate of the outer listview (OuterListView1). Both listviews are bind in the code behind. The outer listview displays correctly in the ItemTemplate. Neither Listview Listview displays in the SelectItemTemplate. Both should display when I click the Select button. I just get a postback (flicker). The display should include the selected record of the outer listview and the inner listview.
I have a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below. Can anyone tell me how to get this to work simply by using the scrollbar to select the number (without having to also click on the number itself) This is the error that is thrown
