Create a Gridview with resizable columns like excel

Please take a look at the screenshot below.
I am trying to create the page with a gridview. The number of column are so many. There are two issues that I am facing here.
1 ) I am using Databale js to provide paging, searching and other facilities. As shown in the screenshot due to large number of columns the search box and paging box are not getting applied on proper place.
2 ) If the column is having a large string , Is there any way we can achieve excel like facility. Where default the overflowed text is hidden and when we click on column to re size it can show the whole value. I am using colresizable plugin for re sizable columns but it is not working as expected.

How to generate freeform rdlc reports with one page per row

Given a data set containing multiple rows, from within a .NET console application I need to generate a report on a single page for each row, sending those pages directly to the printer.
I am attempting to use Microsoft Report for this by attaching it to a data set and placing TextBoxes where I wish. Generating the report and sending it to the printer are not a problem. Unfortunately, the data only seems to be available in aggregates -- First, Sum, Last, Max, etc. I cannot latch the text box to a bare field.
Some poking around here and other sites seems to address this, but only when the data is presented in a table. One post even said without elaboration, "My mistake was using Text Boxes"
Am I using the wrong tool for what I am attempting to accomplish?

I ran into the same problem and managed to solve it. The solution seems a little convoluted to me so don't quote me on the "right" way to do this, but here is what I did:
Make sure you have a Dataset defined for your report.
Add a "Table" control to the report. This seems to be needed in order to iterate the rows in your Dataset.
Delete the header row and two of the default columns from the table so that you are left with a single row with a single column.
Expand the table to the width of your layout and make it as tall as you will need for your "free form" layout.
By default, there is a TextBox inside the table cell. Right-click the empty table cell and choose "delete" to remove that TextBox.
Drag a "Rectangle" control into the empty table cell. It seems to automatically "dock" to the width/height of the table cell.
Now you should be able to drag the fields from your DataSet (TextBoxes, etc) into the Rectangle to produce the desired layout.
Note that I am in the early stages of using this approach so I'm not sure if I am going to hit any walls... but for a basic report that uses TextBoxes and a page break after each "row" it seems to be working ok.

Or you try to use a list.
In the list you can arange textboxes (and other controls) as you want and they will be filled for each record in the recordset.
This work for me. :-)

How to remember formatting options for cells in a gridview

I'm using a GridView that is bound to an object (an entity). The grid can be filtered and otherwise customized in terms of the data it shows. The rows, columns and more specifically cells will be formatted using some rules, but also from the user specifically setting formatting options.
My questions is about the best way to recall the chosen formatting for specific cells. Currently my best method is to store an id for each cell that looks up all of the formatting for that cell (i.e. ForeColor, BackColor, FontWeight etc).
Another way would be to create a new table (called say Formatted_Cells) that stores the id and column name of the table in question, and then the formatting options. This would involve checking the Formatted_Cells table each time a cell is processed to check for formatting. It is quite a bit of processing (similar to the above method). If I did this I could flag any rows that have custom formatting, and if they do not I wouldn't need to check the Formatted_Cells table which does provide an advantage over remembering formatting for EVERY cell, when the vast majority will not have any custom formatting.
Is there a better way? I don't think I can use Serialization to help as the grid is loaded from the database which may be modified elsewhere. But perhaps I'm missing something obvious?
Much appreciated.

I'd suggest an additional table also.
Two possible solutions come to mind:
1- Do the formatting in two passes. First load the grid normally, then read Formatted_Cells table from database, find styled rows in grid and apply special styling.
2- When quering database for Cells, add Formatted_Cells table with left join. When loading grid, check for additional columns that might come from left join, apply those. If no additional columns, style normally.

Dynamic DataGrid columns in WPF DataGrid based on the underlying set of data (and their type)

I've got kind of a conceptual question. I am in the process of wrapping some statistics classes I wrote into WPF.
For that I have two DataGrid(-Views, currently in WinForms). In one DataGrid each row represents a column in the other. There I can set-up different variables (as in mathematical/statistical variables) with fields like "Header", "DataType", "ValidationBehaviour", "DisplayType". There I can also set-up how it should be displayed. Some Columns can automatically be set to ComboBoxColumns, some TextBoxColumns, and so on and so forth.
So, now once I've set-up these Columns I can go to the other grid and enter my data. I may, for instance, have generated (in grid 1) one Column called "Annual Gross Salary" with input of numerical values. Another Column called "Education" with "0=NoEducation", "1=College Level", "3=Universitary" etc. These labels are displayed as text in the combobox and my statistics engine behind then selects the respective value (0-3) for calculations (i.e. ordinal, nominal variables).
Sooo. In WinForms I could basically generate all the columns by hand in code and then add my data in the respective cells/rows. Now in WPF I thought that must be easy to realise. However, yesterday I got started with ICustomPropertyDescriptor which (maybe I was too thick) didn't give me the results I was looking for.
Basically, I just need to be able to dynamically generate columns (and rows) with different Layout, Controls (ComboBox, simple Input, DateTimes) based on the data that I have. But I don't really know how to go about it?
So here in summary:
DataGrid 1
Purpose is to display columns that have been specified in DataGrid 2
In rows, the user can add any kind of data in the rows below the columns that is allowed as to the columns specifications
DataGrid 2
Each row in this grid represents a column in DataGrid 1
Contains fields like Name/Header, DataType, Validation Behaviour, Default Value, Data Formatting, etc.
Also contains a function to be able to set-up how it should be displayed. The user can select from, for instance, ComboBoxColumn (and also add the available options), DateTime, normal TextBox, CheckBox etc.
After finishing adding a row it will automatically appear as a new column in DataGrid 1
I'd appreciate any kind of pointer into the right direction. Thanks very, very much in advance! :)

Look up DataTemplates. They do exactly this. The UI is determined by the related type.
Here is an MSDN article...

ComponentArt: Clear a cell in a grid if it is a certain DateTime

I currently have a ComponentArt Grid, which has a column containing DateTime values. In the even that a certain date is used, we want to keep the cell empty.
Since DateTime is a struct it cannot be null or empty. So I am looking for a way to tell the grid to leave the cell blank if this certain date is bound to the grid.
Any solutions would be greatly appreciated.

When defining a GridColumn you can set it to use a custom client template (or a server template if you need ASP.NET components).
You can have whatever logic you may need there to hide the cell value (You may not print it at all).
For server templates you can see an example here, examples on client templates are in the docs too.
