C# - Datagrid Getting Selected Value (delete Xml Node)?
Dec 26, 2010Lets assume there are 2 columns in my datagrid:
<asp:View ID="viewRemove" runat="server">
<asp:DataGrid ID="dgRemove" runat="server" AutoGenerateColumns="False" OnDeleteCommand="dg_DeleteCommand">
<Columns>
<asp:BoundColumn DataField="name" HeaderText="names" />
<asp:ButtonColumn ButtonType="PushButton" Text="Delete" CommandName="Delete" ></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
</asp:View>
The first column displays names from a xml file and the button column just hold delete buttons so i can delete the corresponding item to the left of it (1st column).
How exactly can i retrieve/pass this selected value to a function? In other words when i press the button to the right of the name, it passes the value so i can work with that to remove the corresponding xml node. (using XPath)
XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Load(file);
XPathNavigator nav = XMLDoc.CreateNavigator();
var node = nav.SelectSingleNode("/root/name['" + ??? + "']");
node.DeleteSelf();
XMLDoc.Save(file);

View 1 RepliesForms Data Controls :: DropDownList In DataGrid Selected Value Not Being Saved On Postback
Apr 13, 2010I have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.
Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.
Forms Data Controls :: Selecting A Row In An Datagrid And Passing A Value Related To Selected Row On Button Click?
Nov 5, 2010I have a datareader that returns a few fields (orderid, customer id, customername, location, total amount - as an example) that is bound to a datagrid on an asp page. The datagrid simply displays customername, location and total amount and has 2 buttons
below it labelled 'Add New' and 'Edit' and I would like the following to happen:
1) when a user clicks on any cell in the datagrid, I want that row to be highlighted in someway so that the user is aware of the highlighted row.
2) If the user then clicks on Edit button, I want to go to another page that displays the details of that order by passing the orderid of that row to the next page.
The idea is that the user selects a row on the datagrid and then clicks edit which will take them to another page where they can edit/updated details but I'm not sure how I can pass a value of a selected row in a datagrid to another page. I am aware that you can add a template column with buttons on but I would like to have one set of buttons rather than have buttons on each row of the datagrid.
Forms Data Controls :: Datagrid Selected Rows Inserted To Different Table From Button Click?
Feb 12, 2010I'm needing to get the selected rows, based on checkboxes, to insert into a different table than that that the gridview is formed from. I've created an innerjoin datasource to try and solve this but, still having problems finding something that works. I also need it to insert based upon a button click not inside the gridview as I believe otherwise would only hamper the situation more.
View 7 RepliesForms Data Controls :: Add The Selected Rows From DataGrid1 Into DataGrid 2 Either With A Button Click Or Using Drag And Drop Functionality?
Jul 8, 2010What I am looking to do is have a page with 2 seperate datagrids on, I want to be able to add the selected rows from DataGrid1 into DataGrid 2 either with a button click or using drag and drop functionality (Im guessing this would require javascript and I have no experience with this language, is it difficult to learn or could I just alter code from elsewhere?). Once the row is added into DataGrid2 I would like to be able to add some information, such as Quantity and DateDue (could this be added in a pop up box when the part is added?) Also I would like fields in DataGrid1 to be based upon a search with several different options that the user specifies, i.e the ability to search based on project number, however it would return eitheer parts or assemblies depending on a check box selected. I have very limited programming knowledge but Im guessing I would be able produce a query based on the inputs, but in order for this to work wouldnt the page to postback everytime an option was changed.

Jul 27, 2010I'm trying to create a web page using Visual C#.NET 2010 on a 3.5 framework that allows users to select items through a series of dropboxes which are then saved to a temporary display grid. The problem I'm having is that I wish to allow users to save multiple combinations of selections which are saved to various rows of the display table.
Below is a sample of what I'm trying to do.

The problem I'm having is whenever I try to edit the selected column all other columns are cleared. I need to have them remain while only the selected row is altered.
Forms Data Controls :: Failed To Load Viewstate When Gridview Control - Replace Gridview With Datagrid
Apr 5, 2010Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.
I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

View 7 RepliesHow To Replace DATAGRID With GRIDVIEW On WEBFORM1
Jul 28, 2010I am using ASPNET2008 I have been asked to replace DATAGRID with GRIDVIEW on WEBFORM1.ASPX.
For Pagination, I am having problem due to lack of knowledge to replace page 1,2,3,4,5,6,7 8, 0 with NEXT , PREV like I did it for DATAGRID. Have to use NEXT and PREV because the GRIDVIEW Pagesize = 20 while the rows from the TBLSALESTRANSACTION exceeded 350rows What I am trying to do is, each time the user click on either NEXT or PREV, This is what I want the GIRDVIEW to display. NEXT the GRIDView should display the next 20 rows and the LBLPAGE.text should display the page number of the current 20 rows, Eg. Page : 2 / 18 PREV the GRIDView should display the previous 20 rows from the current 20 row and the LBLPage.text should display the page number of the current rows, Eg. 1 /18.
Also, How do I determine logically whether it NEXT or PREV being clicked ? And how do I use this FLoadGridView to either display next 20 or previous 20 rows.

View 7 RepliesSorting - Updating DataGrid To A GridView Control
Dec 1, 2010I have a datagrid that is displaying data that is being returned from a stored procedure. That works fine. The problem is that I want to do sorting. I know that there is sorting functionality in the grid, however, I don't want to go back to the server and get a new set of data. What I want to do is just re-sort the data that is already being displayed.
Basically, I couldn't not find an easy solution to this issue. I tried updating my dataGrid to a gridView control and even that (for my particular issue) was difficult. I wound up un-doing all the changes and just adding another grid that had just the data I wanted for the requirement. If anyone else has an issue like this I would recommend taking it out of a datagrid and writing it in jQuery. I could of written a table that had the data I wanted (and fully sortable using a plug-in mentioned below) in 15 minutes compared to the hours I spent trying to jam a square peg into a round hole.

I have an outrageous number like 577 but there's only five or so rows in the grid. Is something left over that is screwing it up?

Forms Data Controls :: On Fly Programatic Datagrid / Gridview In VB
May 12, 2010I have a interesting problem and being relatively new to .NET I thought to try the forum for some guidance. I need to present information from a database, typical, but I need to create stand alone views of the data based on the "category" for the reported information. I don't know how many or how few categories I might need to generate but each needs to be displayed in its own datagrid or gridview. I did a prototype report where I could dynamically generate a variable number of columns in a generic datagrid already placed on the page based on the database but the user "changed their minds", also typical, and want a different view (actually views). Does anyone have any thoughts on creating anywhere from 1 to a dozen (or more) datagrids in the code behind and then pushing them out to the aspx page for the user? Can you dynamically generate datagrids and gridviews on the fly? Or would you need to?
