1) How to bind this xml Using DOM Model to GridView from serverside? I don't want to pull xmldatasource and gridview with columns on FRONT end(aspx).
2) How to dynamically bind the nodes DesignDate, SoldDate....as columns to Gridview, coz there can be many columns with different column names and I don't to specify by saying: HeaderText="DesignDate". I would like to generate this dynamically from serverside.provided with a code to make this working.
let's say we have datatable with "<a>12</a>" as rows.when i try to bind it to gridview programmatically I'm not getting href links like 12 But just a strings like "<a>12</a>"
Code: Dim datatable as new DataTable datatable.Columns.Add("No") dim datarow1 ad DataRow = datatable.newrow() datarow1(0) = "<a>12</a>" datatable.rows.add(datarow1) gridview1.DataSource = datatable gridview1.DataBind()
I used bind all GridViews, DetailViews etc. on my page using an ObjectDataSource (unless it wasn't possible to do so). Recently, I've started binding all my contols programatically. I find this a lot cleaner and easier, though some may disagree. Binding with a ObjectDataSource obviously has it advantages and disadvantages, as does doing it programatically.Say I bind a GridView programatically (e.g. GridView1.DataSource = SomeList), when I change page on the GridView, I have to also code this. Each time the page changes I have to call GridView1.DataSource = SomeList again. Obviously with a ObjectDataSource I don't need to do this. I normally stick my SomeList object into the ViewState so when I change page I don't need to hit the database each and every time.
My question is: Is this how the ObjectDataSource works? Does it store it's data in the ViewState and not hit the database again unless you call the .Select method? I like to try and get the best performance out of my applications and hit the database as few times as possible but I don't really like the idea of storing a huge list in the ViewState. Is there a better way of doing this? Is caching per user a good idea (or possible)? Shall I just hit the database everytime instead of storing my huge list in the ViewState? Is it sometimes better to hit the database than to use ViewState?
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
I have a GridView which pulls info from a SQL DB. It works fine. I use a CMS to upload the data which includes thenumber referred to below.
The last (rightmost) column in the GridView is a number.
I'd like to know how to know how to:
1) Make a further column visible (to the right of the number) which contains a Button BUT only when the user is logged in.
2) Make that Button call a function (the workings of the function are irrelevant here) and pass to that function the number in the previous column.
I know I could use a LoginView with two GridViews, one for logged in (showing the Button) and one for anonymous (without the Button), but then I'd have to put the Button in the database... I think.
A better idea would be to add the Button column programmatically.
how this can be done and how the Button in each row, when clicked, can pass whatever number is to its left as a parameter?
how i can add checkBox in gridview instead of (alpha or beta ) at tbl.row.add for is_active ?when is_active is true then checkbox.checked = true and else if is_active is false then checkbox.checked = false ??
How can I programatically call a gridview row when it is loaded based on the primary key. For example, say I have a record in the gridview where the column name is ID (Identity Field) and has the number 37 in it. When the gridview loads up, I need to get the rowindex where the primary key = 37 and have that row automatically selected.
I have already google the question, but couldn't found any relevant post.1) I want to make gridview's one column () editable according to some boolean value (flag). If flag is true when the edit is clicked, related column would be editable (text field), otherwise related column would be label.2) Same again, I want to make enable delete button in some rows and not some rows according to that flag.
I was wondering what would be the best pratice to databind a gridview programmatically.Normally i put my databind code in the page_load() but is there a way to reduce the number of times the databind method is called?I mean... the page_load() method seem to be called a lots of times when doing callbacks with the grid.
I have a grid in 1st page and one link in it.If i click that link it should open a popup which has a grid and it should bind data according to the row information.In my grid its displaying columns evrything in popup but data is not displayed.
I am converting a VB.net project to c#. I am trying to bind an xml file to a DataGridView, however DataGridView does not have a DataMember property. How do I set the Datamember in C#?
I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
I have a gridview with bound fields and a templateField that receives data from a submit button which, depending upon the selected object, i.e. dropdown 1, 2, or 3, return a result set. The gridview also has a checkbox column which is used as a marker to determinie the rows to be added to and existing table. If a user selects multiple row, those rows are written to the database. Everything works.
Now, I need to add additional functionality to the gridview:
Upon selecting the checkbox, programmatically the accompanying row must become editable; for each row presented.
Deselected the checkbox, return the gridview row to a read-only state.
There are 14 columns, one of which is a dropdown which needs to maintain its default value.
[inFrmDate] (this is the key field), [inFrmData], [totFrmData] (this accepts nulls)When I try to add [inFrmDate], [inFrmData] to the GridView I get the messageto the effect that the:
we're creating a GridView to display news articles programmatically (not using a SQL database).
We can create & display the GridView, but are having a devil of the time to get the hyperlinks in SetupGrid() attached to the titles
of the articles in the GridView. Below is our .aspx code and .vb code of how we create the GridView. Any ideas on what we should do to get the hyperlinks array of strHyperlinks() in SetupGrid() to be applied to the titles in column 1 of the GridView?
