I am working on a SSRS report, in which i have a dataset in which some of the rows are completely empty strings. And the report runs on a selected parameter value. When I select a parameter value and if all the column values for that parameter value is an empty string, then the result is displayed as an empty table.
But instead I would like to display it with an error message as "No data available for the selected parameter".
Please help me with this. Thank you.
You could set the grids' NoDataRows message to be this.
NoRowMessage don't work for an empty table I guess.
Instead what I did was, I added an extra row above the empty row in the table(i.e., in between the column headings row and the details row) that is being displayed when the selected parameter doesn't have any data. And I merged all the cells, then wrote whatever error message that I wanted to display. Then I change row visibility of that row to
Show or Hide based on an expression
and the expression I used is as follows
-- This expression is to hide the row -- True --> Hide, False --> Show
=IIF(Fields!Field.Value <> " ", True, False) -- In case if the row you want to hide contains a field value that is empty.
Then change the row visibility of the details row to
=IIF(Fields!Field.Value = " ", True, False)
The first expressions displays the row when the table is empty. And the second expression displays the details rows when the table returns any values.
Hope this helps to someone who faces the same issue. If anybody has anymore doubts regarding this they can reply me back here.
Thank you.

Would you help me, please, to retrieve column name by query.
In the report I want to show columns by condition.
I created a parameter #cols, which contains the list of column names (multiple values are allowed).
In column visibility/show or hide based on expression I added:
=IIF(InStr(Join(Parameters!cols.Value, “,”), “My_col_name”)=0, true, false)
This works perfectly, but for each column I should insert in the row above the original column instead "My_col_name".
Since my report has hundreeds of columns, it looks annoyying.
Is there a method to simplify this task? E.g. to insert instead "My_col_name" some expression, which shows selected column name?
Thank you.
I have a store procedure which brings the data as shown below . I'm new to SSRS reporting, I would like to show only those row where "email" column is null. How can i achieve it in SSRS ? As i mentioned I'm very new to this , any screenshot will help me a lot. Thank you for your time.
For this problem, you'll want to change the row visibility to hide rows with a value in that column. I assume you're using a table or matrix to layout this data. You'll want to right click on the row where your data fields are entered. Specifically, the grey box at the left of the row.
From there, you'll need to select the option to Show or hide based on an expression.
And finally, you'll need to enter an expression that finds the values in the email field. I'm not exactly sure what the field names are called but something like the following expression should do it.
= Not IsNothing(Fields!EmailField.Value)
This will check the field where you get the email value with a built-in function of IsNothing. Additionally, since you want fields that do not contain values, the Not keyword reverses the results. If the function evaluates to true and a value is present, the row will be hidden and vice versa.
I have a combo box in a form that uses a query to get the row source (lookup list). I am trying to set the default value to blank but nothing seems to work. It still populates with the first row of the query result. I am thinking it may be because there is no blank value in the list.
Here are the properties I have currently:
Limit to list - No
Allow Value List Edits - Yes
Inherit Value List - No
Show only row source values - No
Default Value ""
Any help is appreciated
I'm trying to achieve my report displaying a "No Data Available" message if no results are returned in my query.
I am trying to achieve this via an expression against the Row Visibility.
So I have a Tablix that looks like this -
If there is data available then I want the third, fourth and fifth line to show.
If no data exists then I want the first two rows to display.....
In the Row Visibility for the first two rows I have the following -
=iif(CountRows("RentTransactions") = 0, true, false)
In the Row Visibility for the remaining three rows I have the following -
=iif(CountRows("RentTransactions") > 0, true, false)
I have a filter on the Tablix that just limits it to "AccountType" = Water.
When I run the report between 01/06/2016 and 30/06/2016 - I know there are not transaction - so would expect my report to return the first two rows....
It doesn't it returns the bottom ones , with no data in it??
What am I doing wrong?
The DataSet is definitely called RentTransactions
There are a few issues going on here.
CountRows with the dataset name will always return the total number of rows in the entire dataset.
Row Visibility will make the entire row blank, but it will still take up space. This would look bad if there are alternating blank rows.
What you're really trying to do is control what is displayed in each cell. So in each cell you'll want to have an expression that checks whether or not to display a value. For example, for the Description field it would look something like this:
=IIf(Count(Fields!Transaction_Type.Value) > 0, Fields!Description.Value, "")
This expression will work by returning a count of 0 for NULL Transaction Types. You can customize this if needed.
Also make sure that the query is returning rows for dates with no transactions. Otherwise there's no raw data for the report to do anything with in the first place.
I have my report and data ready. The report is like i need to select a center name (Ex: Raleigh(0003) ) from the DDLB. and i will submit that. Now i will get the report for the Raleigh Center. Here, i need to see the text on the top of the report like "Weather Report for Raleigh (0003)" as a header. Whenever i select a different center, it should automatically display that particular center on the top of the report.
I tried to add the table, give the column (CENTER_ID) from the data set and in the expression, i gave like --> ="Weather details:"& Fields!CENTER_ID.Value &" - " & Fields!CENTER_NAME.Value. Here is the issue, it's either displaying all of the centers row by row or displaying a particular center name irrespective of the selection. Please help me out as it is very important.
Thanks.
When you select a center from the drop down - it is populating a parameter that you must then be using either to filter the query or to filter the table. Depending on how many rows the full query returns it might be better to do one or the other, e.g. if there are 1000's of rows you should filter the query, not the tablix. If it's not many rows then it's fine to filterthe tablix.
If the parameter is called #center then you could use this formula in your header:
="Weather details: "& Parameters!center.value
This assumes that your paramater is "text" type. If it is numeric or a date then you might have to convert it to a string first using CStr().
="Weather details: "& CStr(Parameters!center.value)
The reason it was showing you a "particular center name irrespective of the selection" is because you were telling it to put a dataset column (many rows) into a single cell. That will force it to always display the value in the first row, or if you are putting it in a details row in the tablix it will output every single value.
If you filter the query rather than the tablix, you could reliably use this:
="Weather details:"& First(Fields!CENTER_ID.Value,"datasetname") &" - " & First(Fields!CENTER_NAME.Value,"datasetname")
because the first() function will return a single value from the first row of the dataset.
