Forms Data Controls :: Programmatically Creating Chart Control And Adding It To Dynamically Generated Table?
May 21, 2010I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

Forms Data Controls :: Building A GridView Programmatically?
May 9, 2010I 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.
Forms Data Controls :: How To Add Column To A GridView Programmatically
Nov 17, 2010I 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?

Forms Data Controls :: Programmatically Select A Gridview Row?
Feb 12, 2010How can I programatically call a gridview row when it is loaded based on the primary key.

Jan 4, 2011I 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).

View 1 RepliesForms Data Controls :: Adding Row In GridView Programmatically?
Feb 12, 2010I have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#

Forms Data Controls :: How To Hide Gridview Column Programmatically
Mar 24, 2010I'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.
//From class file
[Code]....
//From webform
[Code]....
In this example, I want to hide the ID column.
Forms Data Controls :: Make A Gridview Editable Programmatically - Per Row
Nov 3, 2010 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.

Forms Data Controls :: How To Set Gridview's 2nd Column Formatting Programmatically
Jun 21, 2010I have a Gridview and I want to format 2nd column of it to {0:dd-MMM-yy}
If it is not autogeneratedcolumn Gridview I would have used DataFormatString="{0:dd-MMM-yy}"
However, this time it is a autogeneratedcolumn Gridview so I cannot use the above code anymore.
So can I set that column format programmatically ?
I tried
GridView1.Columns(1).
But then there is nothing close to dataformat pops up from intellisense.

View 5 RepliesForms Data Controls :: Programmatically Put The Gridview In Edit Mode?
Feb 2, 2010I have a webform with two gridviews; a textbox for the invoice number, and a button to kick everything into action. I programmatically handle the select statements in the VB.Net file because I need to iterate through the second gridview's table to perform calculations and then put those results into the first gridview's table. Then I bind them. It works just fine.
The first gridview has one row with the payment information. The second gridview has multiple rows with the items that the payment is handling.Now I need to handle the edit, update and cancel functionality. I tried using a sqlDataSource for edit, update and cancel because it is simple, but it requires a Select statement so I guess that idea is not going to happen. I put a commandField with showeditfield=true, but clicking edit gives an error that rowEdit isn't handled. I have put that sub gvInvoice_RowEditing in there, but being new at this I have no idea what to put into that sub.
I can programmatically create all that functionality in the code behind. Won't it be quicker and easier if I write sub's for Edit, Update and Cancel that tell the gridview what to do - trick it to automatically handle all that? Is there an example available demonstrating how to tell the gridview to go into edit mode and proceed as if it was using a sqlDataSource?As a final note: perhaps it would be simpler if I create a third gridview to handle the job of totaling all the cash and listing each check seperately.Here is my code. It probably isn't the most elegant approach, but it works.

Forms Data Controls :: Programmatically Iterate Through Different Pages In A GridView?
Oct 4, 2010I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?
