SQL Reporting :: Assign Empty Dataset To The Tablix Or Conditionally Change The Dataset For The Tablix Based On A Parameter?
May 4, 2010
I have a paramater Country Which have options to select 10 different countries.. i am using 10 tablix one for each country .... When i select a country , only one tablix Gets visible and the other 9 tablix gets invisible.. The problem is that all the invisible tablix are calling sp that is dataset ... Cause it is reducing the performance of the report......how can i assign empty dataset to the tablix or conditionally change the dataset for the tablix based on a parameter...
This is the format of my report and I am trying to get the rows sorted.I do know about interactive sorting but I do not want to use it because this report will be called by an external web application and I want this report sorted before it is rendered to the user.
[code]....
I want this to be sorted by the second column in a descending order 5.0,4.0,3.0,2.0,1.0. I rightclicked the matrix,selected the sorting option and chose the grouping name( "Index" in my case) and chose Z to A (Desc I presume), saved and deployed to the server and when the report rendered it was not sorted by the second column(grouping).
Is it possible to achieve this? Does the report always render based on the first grouping in the ascending order (like Agree,Disagree...)
I am using tablix and use row and column grouping ,on column grouping column text is getting displayed in top to bottom formet but i want to display in bottom to top formet .
I m using SQl server 2005 reporting..I have used two datasets for a report.
In one dataset i m passing a parameter and i want to pass that parameter to another dataset.So that i dnt need two paramerters when i preview the report.
Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.
How to assign a array string session to dataset or datatable? I have a array session data in that i stored n number of values. i want to assign these values to dataset. so that i can bind these values to gridview. so anyone pls let me know how to do this? Iam getting error to convert sesion{"noncontractitem"] to datatable.
I am looking to cache a dataset and then filter the results as they will be used repeatedly. However, I don't know how to assign values in the filtered dataset to variables in C#. I have looked on the internet for the past few hours but all I can get in binding the dataset to a control.
i want to merge all the dataset table in one dataset is working fine . if it is empty dataset means it rejects that datatable but i want to show the col name with empty values for that i want this below format
I dont know why my GridView.DataSource is become nothing when the Page.IsPostBack = true.What i did is bind the dataset to the GridView.DataSource when page load. Then when the button click event is trigger i need to get all the records from GridView. But when i debug and check i found that the GridView.DataSource is become nothing. how should i get all records from the GridView and assign to dataset. I'm using VB.net to work on.
In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:
I am looking to retrieve data from a database and assign those values to class objects which in turn will be turned into session variables. I am using an object datasource to retrieve the data from the database but I cannot find anywhere that shows how to assign these values to variables. The data is returned in a dataset. There is the added problem that there will be mulitple items returned which will have to be assigned to different arraylists of objects based on the a primary key in the database.
What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.
I want to do ReportViewer, and i want have created a DataSet. I fail to drag the data table from ToolBox. My ToolBox doesn't exist any data table. The output i want to archive is something like this in my DataSet
If ispostback = false then dsDataSet = ..... END IF
Now I have a button where when clicked..
dsDataSet = anotherdataset...
Now I have 1 button that all what it does is loop through the dataset..
For each row in dsDataSet.tables(0).rows
Now the problem is that when I click on the last button, it says (cannot find table 0) which means the dataset is empty, why does the info in the dataset get removed on the postbacks? how can I avoid this?

i am using asp.net 2.00(visual studio 2005 std edition) i have designed a report in reportviewer which runs fine on localhost server but when deployed on server it shows no data from other computers , after searching net i found that dynamic binding of dataset and reportviewer is required , so i entered following codes (dtgraph is data table name and graph.axd is data set name ) the code gives error that dtgraph is not declared , where i should declare it / any solution

I have created a DataSet which is connected to an Access Database. This DataSet is linked to a report and I would like to apply a filter to only display information relevant to the logged in user. My question is, if I wanted to add a parameter to the filter in my DataSet, what is the correct syntax when entering parameters? Whatever I try, it seems to convert automatically to a string.
I'm new to creating reports. I created a report rdlc, and created three report parameters and placed in data region. See the code below
[Code]....
When I build this..I got the error saying "The table 'table1' is in the report body but the report has no data set. Data regions are not allowed in reports without datasets. "
I need to create rdlc without dataset and to bind dataset at runtime.
I have to display the report, For this i have used stored procedure that returns the complete dataset for the reporting.
The scenario is that, In SP there is ID instead of actual display name, and i need to display the name. The actual problem is that to get the name instead of ID, we have to query in another DB.
So,
Is it possible to query to another DB to get Name instead of ID ??
Or,
Can we pass the complete Dataset to the report viewer page from the ASPX page. As in the aspx page it is easier to calculate the name from ID.
