Change Text Object Value of Crystal Report Dynamically in VB.net
提问by Jay Marz
I have this picture of my current format of crystal report.
我有这张水晶报告格式的图片。
My problem is, I want to set the value of fullNamefield dynamically depending on the query result of my vb.net form. For example, I have this code from my vb form,
我的问题是，我想fullName根据我的 vb.net 表单的查询结果动态设置字段的值。例如，我的 vb 表单中有这个代码，
sql = "SELECT fullName FROM tblClient WHERE clientID = '" & ST-TAC-23 & "'"
da = new SqlDataAdapter (sql, con)
dt = new DataTable
da.fill(dt)
I want the dtvalue to be passed on fullNameobject in my crystal report. For example the dtvalue is Mark Zucker, I want the fullNamefield in my cr to display Mark Zucker also. How could possibly do that?
我希望将dt值传递给fullName我的水晶报告中的对象。例如，dt值是 Mark Zucker，我希望fullName我的 cr 中的字段也显示 Mark Zucker。怎么可能这样做？

I have found out the best trick for this problem. This is how I fixed it.
我已经找到了解决这个问题的最佳技巧。这就是我修复它的方式。
In the loadevent of the form (form for crystal report viewer), I coded this lines,
在load表单（用于水晶报表查看器的表单）的情况下，我对此行进行了编码，
Dim fName As TextObject
fName = rptDoc.ReportDefinition.ReportObjects("crFullName")
' display the value for the report
fName.Text = frmAccInventory.lblName.Text
Where "crFullName" is the name of the text objectin crystal report. rptDocis declared at frmAccInventory as new crystalReport1 (name of the crystal report file)
其中“crFullName”是text object水晶报表中的名称。rptDoc在 frmAccInventory 中声明为新的 crystalReport1（水晶报告文件的名称）
