Forms Data Controls :: GridView,calculate Value Based On Other Columns& Save To Datasource?

Nov 8, 2010

I had just started with Visual Studio 2008 + I've now designed my tables, and basic gridview functions properly.Now I'm faced with the problem of having to calculate a value based on 2 - 3 columns/data in the gridview, display the result in an existing column in the same gridview, and saving the calculated value in the datasource.I had initially created the "Total" column as a textbox displaying a manually calculated amount that is saved in the datasource. Now, I want to change the field to auto-calculate based on 2 other columns.

Forms Data Controls :: Gridview-Calculate Value Based On Formula That Varies Dependent On Selected Code In Dropdownlist?

Jul 2, 2010

GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".

I am fairly new to, vb, forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.

I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

DataSource Controls :: Search Various Database Columns Based On User's Input?

Nov 18, 2010

I have five textboxes(tb1, tb2, ... tb5) on the page, each textbox represent a column in the database table.

I need to search the database table based on the text in the textboxes. User can either enter text in all five textboxes or none.

What's the best way to do a search?

I am thinking for one textbox(tb1), depends on if tb1.text is empty or not, I need to do 2 searches


for two textboxes(tb1 & tb2), depends on if tb1.text and/or tb2.text are empty or not, there are 4 combinations, so I need to do 4 searches


for three textboxes, there are 8 combinations,

Does that mean for five textboxes, I need to do 2 to the power of 5, 32 combinations, 32 if statements?

VS 2008 - How To Calculate Between Two Columns In Gridview Control

Jan 6, 2012

I have a simple gridview control on .aspx page. It has one combo box in the gridview control and rest of the columns in the gridview control are all bound controls.

When the user picks something from combo box, I should multiply the number (picked from the combo box) with other number in the same row (meaning in a different column on the same row). I want to do all this in server controls not thru JQuery or Javascript.

Basically my problem is I am able to read data from unbound combo box control in the grid. But I should be able to read the contents of another bound column in the same row and perform multiplication between those two fields.

<asp:GridView ID="GridViewActuals" runat="server"
DataSourceID="SqlDataSource1" DataKeyNames="gl_number"
onrowcommand="GridViewActuals_RowCommand" Height="285px"
Font-Names="Verdana" onrowupdating="GridViewActuals_RowUpdating1">

Data Controls :: Calculate Textbox Value Based On If Condition Inside Stored Procedure

Jul 17, 2015

I have 3 Textboxes in my Web page. When user key in value in these 3 textboxes,their result should show on a "Label"

1) Gross Amount
2) Taxable Amount
3) Tax Amount

I have to write a Stored Procedure for calculating the value of above textboxes.

Condition is:

If Gross Amount is > or < 0.00, then Taxable and Tax amount should calculate based on below formula:
@TaxableAmt = @GrossAmt / @Rate
@TaxAmt = @GrossAmt - @TaxableAmt

but If Taxable Aount is > or < 0.00, then Gross and Tax amount should calculate based on below forumla:

@GrossAmt = @TaxableAmt * @Rate
@TaxAmt = @GrossAmt - @TaxableAmt

and for "Tax Amount" I have 2 different conditions:

If Tax Amount is = 0.00, then Taxable and Gross amount should calculate based on below formula:
@TaxableAmt = @TaxAmt / (@Rate-1)
@GrossAmt = @TaxAmt + @TaxableAmt

but If Tax Amout is <> 0.00, then whatever the value of Tax Amount is, it should key-in/show as it is.

i.e., @TaxAmt = @TaxAmt

For this requirement, I wrote below SP:

ALTER PROCEDURE [Invoice].[usp_tbl_TaxCode_Update]
-- Add the parameters for the stored procedure here
@TaxCodeID nvarchar(50) ,
@GrossAmt decimal(18, 2),
@TaxableAmt decimal(18, 2),
@TaxAmt decimal(18, 2)


But its not working as per required.

DataSource Controls :: GridView To Display The Data Based On One Or The Other?

Apr 5, 2010

I have a web form with two drop downs.I want the gridView to display the data based on one or the other.The user can then select a record to be displayed in a detail view.This method works as long as I am only viewing the data.If the user edits the data in the detail View and then updates the detail view when the page reloads the grid goes blank.I have traced the code and there is data in the query after the update but the select statement for the LinqDataSource is overriding the code in the lqGrid_Selecting.I can make the above scenario work using SqlDataSources,but I thought LinqDataSources were the way of the future.

Forms Data Controls :: How To Hide/show Columns Based On The Dropdownlist Value

I have an emergency request that I need to sort it out very quickly as I did not notice it early :(.

I have a dropdownlist, the contnet in the gridview (sqldatasource connection) changes based on the value the user slects, say I have play1, play2 from the dropdownlist, I would like to show column1, column2 and column3 with user selects play1; show column4, column5, and clomn6 when use selects play2; the datatable actually includes all 6 columns.

I understand that I need to use something like RowCreated event, and I need to set up condition based on the dropdownlist value, but I dont really know how to.

Forms Data Controls :: Making Columns Invisible Based On Data?

Dec 22, 2010

I am trying to make columns of a gridview invisible if they contain a space. The page contains a combo box which users can change. This causes a change in the data in the gridview. I use the following code:



What is working: On the initial page load, the correct columns are deleted. However, if the user changes the combo box, and the gridview has different data loaded into it, it cannot make visible what was previously invisible. I added the ...visible = true line to get round this, but when I load the page, it seems to get locked into a loop forever, and the page never loads - this is why the line is commented out.

This should be soooo simple, but it's making my brain smoke. I've tried writing the results on whether there is a space in the cell to an array, and then using that to make the columns invisible. I've tried doing this in different events, but it always has the same problem.

I suspect that if I can find out how to reference the contents of the gridview from outside its events, it may be easier.
