How to read control / variable value in rdlc? - expression

I want to display the value from dropdown on aspx page to the rdlc header.
how can i achieve this.

Create a text parameter for your report to accept the value, then add a label to your report header and enter an expression such as =Parameters!TheDropDownText.Value for its value; you'll need to supply the report parameter its value when you run the report, but that's another topic :)

SSRS expression display custom text

Can i make field value hidden within Expression in SSRS because i don't want to display this integer value?
For instance: I placed text box where I created simple Expression:
="Click for Details" & Fields!LocationId.Value
Fields!LocationId.Value is my specified parameter where I link Main report ID and Details report ID
I use Action within cell column to redirect to subreport based on unique LocationId.Value where user will click on the line with wording "Click for Details".
When report runs I have in each cell :Click for Details3636
Click for Details7239
and so on..
is mission impossible here??!!

BIRT Dataset Parameter Placeholder not Created

The BIRT documentation states that when I add a ? marker in the where clause of the SQL query, BIRT will automatically create a placeholder parameter that I can then edit appropriately. I've added the markers, but nothing ever appears in the Parameters list for the dataset. Am I missing something? If I create a parameter without first having a placeholder, can I somehow associate it with the appropriate marker in the query?
The parameters are not generated automatically.
You'll have to add them manually.
After finishing the SQL SELECT statement, edit the Data Set and choose the entry "Parameters" from the menu on the left side. Then, for each "?" in the select, add a parameter using the "New..." button on the right side.

How to Hide/Show of UI component in oracle adf

I am new to oracle adf in my application one of the field is id and it is sequence generated value Whenever I entered remaining values and click on save then only it has to display with sequence generated value before saving it has to be in hide mode. Can any one help me how the approach is.
set visible property for seq field. like below
visible="#{binding.filedName.inputValue != null}"
by default seq field value is null so it will not display. once u click save button, this field value to be set to next seq value so it will display
Just remove this value from UI and do your number generation for this field in model.
You can set the visible attribute of the field in your page to be based on an expression language such as #{viewScope.showfield}, then add a setPropertyListener to your save button that sets the #{viewScope.showfield} to true.

Can you get value from SubReport?

I have a SubReport with a textbox, I would like to read the value of this textbox and then put it in the main report for each data row.
My SubReport is in a data column.
If you are using Visual Studio, you should be able to drag and drop the sub report object into the text box and configure it from there. But make sure that if the sub report expects parameters, you send the required parameters.

Displaying Popup alert for SSRS Parameter validations

I am working on a SSRS report which has From & To date as input parameters and it has to be validated such that From date can't be more than To date.
I was successful in creating a custom VB code which takes care of validation but the problem is when the validation fails i need to display a user friendly pop up alert which i am not able to do. I tried giving the alert using MsgBox (VB.NET) and also tried calling Response.Write inside javascript, but none of these works.
Help me in getting this done.
Following are the steps that you can follow to achieve this.
In the code section of the report add the following code.
Public Function SelectedMore( ParamCnt As Integer ) As Boolean
Dim Cnt As Boolean
Cnt = IIf(ParamCnt < 4 , 1, 0)
Return Cnt
End Function
Add a text box on the report layout page and add contents to it saying user has selected more than 3 parameter values. You can make this bold and red if you want.
Then go to the properties of the above text box and go to ‘visibility’ tab. Select ‘Show or hide based on the expression’ and add the following expression in the box ‘=Code.SelectedMore(Parameters!HeatMapList.Count)’. This will make this textbox visible only when more than 3 values are selected.
Now go to the parameters of the main dataset ( the onw which fetches the results for you), go to the parameters tab and next to parameter HeatList, click the expression button (fx). In the expression box type in the following code, =IIf(Parameters!HeatMapList.Count > 3, Nothing, Parameters!HeatMapList.Value). This will not pass any value to your main dataset for the parameter and results would return empty. You can alternately add the visibility expression inverse to that of the above textbox, for the main tablix. This will hide the table when textbox is displayed and vise-versa.
